77621940 ÷ 688 
Our goal is to divide 77621940 by 688.

Advancing to step 1:
688 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 688

On to step 2:
If we divide 77 by 688, we get 0 and a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Take the next digit (6) from the dividend and append it to 77, then repeat: 776 / 688

On to step 3:
If we divide 776 by 688, we get 1 and a remainder of 88.
The next digit of our result is 1. 
Result so far: 1.0
If we take 688 away from 776, we end up with 88.
Include the next digit (2) from the dividend after 88, then repeat: 882 / 688

Let's proceed to step 4:
If we divide 882 by 688, we get 1 and a remainder of 194.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 688 from 882 leaves us with 194.
Grab the next digit (1) from the dividend, add it to 194, then carry on: 1941 / 688

Advancing to step 5:
688 goes into 1941 2 times with a remainder of 565.
Write down 2 as next digit of the result. 
Result so far: 112.0
Subtracting 1376 from 1941 leaves us with 565.
Grab the next digit (9) from the dividend, add it to 565, then carry on: 5659 / 688

On to step 6:
When dividing 5659 by 688, we get 8 with a remainder of 155.
Use 8 as the next digit of our solution. 
Result so far: 1128.0
The remainder is 155 after subtracting 5504 from 5659.
Include the next digit (4) from the dividend after 155, then repeat: 1554 / 688

Advancing to step 7:
When dividing 1554 by 688, we get 2 with a remainder of 178.
Write down 2 as next digit of the result. 
Result so far: 11282.0
Subtract 1376 from 1554 to get 178.
Bring next digit (0) of the dividend behind the 178 and repeat the process: 1780 / 688

Step 8:
688 goes into 1780 2 times with a remainder of 404.
The number 2 becomes the next digit in our result. 
Result so far: 112822.0
If we take 1376 away from 1780, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Advancing to step 9:
688 goes into 4040 5 times with a remainder of 600.
Use 5 as the next digit of our solution. 
Result so far: 112822.5
The remainder is 600 after subtracting 3440 from 4040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 10:
688 can be fit into 6000 8 times, resulting in a remainder of 496.
Write down 8 as next digit of the result. 
Result so far: 112822.58
Subtracting 5504 from 6000 leaves us with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Let's proceed to step 11:
688 can be fit into 4960 7 times, resulting in a remainder of 144.
The next digit of our result is 7. 
Result so far: 112822.587
Subtract 4816 from 4960 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 12:
688 goes into 1440 2 times with a remainder of 64.
The next digit of our result is 2. 
Result so far: 112822.5872
Subtracting 1376 from 1440 leaves us 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.

Advancing to step 13:
688 can be fit into 640 0 times, resulting in a remainder of 640.
The next digit of our result is 0. 
Result so far: 112822.5872
If we subtract 0 from 640, we get 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:
When dividing 6400 by 688, we get 9 with a remainder of 208.
Use 9 as the next digit of our solution. 
Result so far: 112822.587209
If we take 6192 away from 6400, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 15:
The number 688 fits into 2080 3 times, leaving a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 112822.5872093
The remainder is 16 after subtracting 2064 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 16:
The number 688 fits into 160 0 times, leaving a remainder of 160.
The next digit of our result is 0. 
Result so far: 112822.5872093
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The quotient of the division is 112822.5872093, and the remainder is 1.6e-07.
