We look at the division of 53544391 by 688 
We want to figure out the number of times 53544391 can be divided by 688.

Step 1:
688 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 688

On to step 2:
53 divided by 688 is 0 with a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Bring next digit (5) of the dividend behind the 53 and repeat the process: 535 / 688

Advancing to step 3:
688 goes into 535 0 times with a remainder of 535.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 535 after subtracting 0 from 535.
Take the next digit (4) from the dividend and append it to 535, then repeat: 5354 / 688

Let's proceed to step 4:
5354 divided by 688 is 7 with a remainder of 538.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 4816 from 5354 and we're left with 538.
Append the next digit (4) from the dividend to 538 and continue with: 5384 / 688

Going ahead to step 5:
5384 divided by 688 is 7 with a remainder of 568.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
The remainder is 568 after subtracting 4816 from 5384.
Take the next digit (3) from the dividend and append it to 568, then repeat: 5683 / 688

Moving on to step 6:
5683 divided by 688 is 8 with a remainder of 179.
Write down 8 as next digit of the result. 
Result so far: 778.0
Subtract 5504 from 5683 to get 179.
Fetch the next digit (9) from the dividend, attach it to 179 and continue: 1799 / 688

Let's proceed to step 7:
The number 688 fits into 1799 2 times, leaving a remainder of 423.
The number 2 becomes the next digit in our result. 
Result so far: 7782.0
If we subtract 1376 from 1799, we get 423.
Include the next digit (1) from the dividend after 423, then repeat: 4231 / 688

Let's proceed to step 8:
688 can be fit into 4231 6 times, resulting in a remainder of 103.
Record the quotient 6 as the next digit in the result. 
Result so far: 77826.0
Subtracting 4128 from 4231 leaves us with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Let's proceed to step 9:
The number 688 fits into 1030 1 times, leaving a remainder of 342.
Use 1 as the next digit of our solution. 
Result so far: 77826.1
Subtracting 688 from 1030 leaves us with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Moving on to step 10:
The number 688 fits into 3420 4 times, leaving a remainder of 668.
Write down 4 as next digit of the result. 
Result so far: 77826.14
The remainder is 668 after subtracting 2752 from 3420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

Advancing to step 11:
The number 688 fits into 6680 9 times, leaving a remainder of 488.
Use 9 as the next digit of our solution. 
Result so far: 77826.149
Subtract 6192 from 6680 to get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Going ahead to step 12:
688 can be fit into 4880 7 times, resulting in a remainder of 64.
Use 7 as the next digit of our solution. 
Result so far: 77826.1497
Deduct 4816 from 4880 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 13:
688 can be fit into 640 0 times, resulting in a remainder of 640.
Record the quotient 0 as the next digit in the result. 
Result so far: 77826.1497
If we take 0 away from 640, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Advancing to step 14:
688 goes into 6400 9 times with a remainder of 208.
Record the quotient 9 as the next digit in the result. 
Result so far: 77826.149709
Subtract 6192 from 6400 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 15:
The number 688 fits into 2080 3 times, leaving a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 77826.1497093
If we take 2064 away from 2080, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 16:
688 can be fit into 160 0 times, resulting in a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 77826.1497093
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

After the division, we end up with 77826.1497093 and a remainder of 1.6e-07.
