Let's divide 43478663 by 553
We want to figure out the number of times 43478663 can be divided by 553.

Advancing to step 1:
When dividing 4 by 553, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 553

On to step 2:
When dividing 43 by 553, we get 0 with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Take the next digit (4) from the dividend and append it to 43, then repeat: 434 / 553

Advancing to step 3:
If we divide 434 by 553, we get 0 and a remainder of 434.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 434 leaves us with 434.
Append the next digit (7) from the dividend to 434 and continue with: 4347 / 553

Going ahead to step 4:
When dividing 4347 by 553, we get 7 with a remainder of 476.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 3871 from 4347 and we're left with 476.
Bring next digit (8) of the dividend behind the 476 and repeat the process: 4768 / 553

Let's proceed to step 5:
When dividing 4768 by 553, we get 8 with a remainder of 344.
Write down 8 as next digit of the result. 
Result so far: 78.0
If we take 4424 away from 4768, we end up with 344.
Include the next digit (6) from the dividend after 344, then repeat: 3446 / 553

Advancing to step 6:
553 can be fit into 3446 6 times, resulting in a remainder of 128.
Use 6 as the next digit of our solution. 
Result so far: 786.0
Deduct 3318 from 3446 and we're left with 128.
Take the next digit (6) from the dividend and append it to 128, then repeat: 1286 / 553

Going ahead to step 7:
1286 divided by 553 is 2 with a remainder of 180.
Put 2 as the next digit of the answer. 
Result so far: 7862.0
Deduct 1106 from 1286 and we're left with 180.
Append the next digit (3) from the dividend to 180 and continue with: 1803 / 553

Moving on to step 8:
The number 553 fits into 1803 3 times, leaving a remainder of 144.
The number 3 becomes the next digit in our result. 
Result so far: 78623.0
The remainder is 144 after subtracting 1659 from 1803.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 9:
When dividing 1440 by 553, we get 2 with a remainder of 334.
Put 2 as the next digit of the answer. 
Result so far: 78623.2
If we take 1106 away from 1440, we end up with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

On to step 10:
The number 553 fits into 3340 6 times, leaving a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 78623.26
If we take 3318 away from 3340, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 11:
The number 553 fits into 220 0 times, leaving a remainder of 220.
Record the quotient 0 as the next digit in the result. 
Result so far: 78623.26
The remainder is 220 after subtracting 0 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 12:
If we divide 2200 by 553, we get 3 and a remainder of 541.
Put 3 as the next digit of the answer. 
Result so far: 78623.2603
If we take 1659 away from 2200, we end up with 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Advancing to step 13:
The number 553 fits into 5410 9 times, leaving a remainder of 433.
Write down 9 as next digit of the result. 
Result so far: 78623.26039
The remainder is 433 after subtracting 4977 from 5410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

On to step 14:
553 can be fit into 4330 7 times, resulting in a remainder of 459.
Record the quotient 7 as the next digit in the result. 
Result so far: 78623.260397
If we subtract 3871 from 4330, we get 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Step 15:
The number 553 fits into 4590 8 times, leaving a remainder of 166.
Put 8 as the next digit of the answer. 
Result so far: 78623.2603978
If we subtract 4424 from 4590, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Moving on to step 16:
If we divide 1660 by 553, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 78623.26039783
If we take 1659 away from 1660, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 78623.26039783 and a remainder of 1e-09.
