Let's divide 77938891 by 687
We're looking to find how many times 687 goes into 77938891.

Step 1:
687 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 687

Step 2:
687 can be fit into 77 0 times, resulting in a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Fetch the next digit (9) from the dividend, attach it to 77 and continue: 779 / 687

Let's proceed to step 3:
If we divide 779 by 687, we get 1 and a remainder of 92.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 687 from 779 and we're left with 92.
Fetch the next digit (3) from the dividend, attach it to 92 and continue: 923 / 687

Advancing to step 4:
687 goes into 923 1 times with a remainder of 236.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 687 from 923 to get 236.
Include the next digit (8) from the dividend after 236, then repeat: 2368 / 687

Step 5:
2368 divided by 687 is 3 with a remainder of 307.
The number 3 becomes the next digit in our result. 
Result so far: 113.0
The remainder is 307 after subtracting 2061 from 2368.
Grab the next digit (8) from the dividend, add it to 307, then carry on: 3078 / 687

Going ahead to step 6:
3078 divided by 687 is 4 with a remainder of 330.
Record the quotient 4 as the next digit in the result. 
Result so far: 1134.0
Deduct 2748 from 3078 and we're left with 330.
Fetch the next digit (9) from the dividend, attach it to 330 and continue: 3309 / 687

Advancing to step 7:
When dividing 3309 by 687, we get 4 with a remainder of 561.
Write down 4 as next digit of the result. 
Result so far: 11344.0
Subtracting 2748 from 3309 leaves us with 561.
Grab the next digit (1) from the dividend, add it to 561, then carry on: 5611 / 687

On to step 8:
The number 687 fits into 5611 8 times, leaving a remainder of 115.
Use 8 as the next digit of our solution. 
Result so far: 113448.0
If we take 5496 away from 5611, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 9:
The number 687 fits into 1150 1 times, leaving a remainder of 463.
Write down 1 as next digit of the result. 
Result so far: 113448.1
The remainder is 463 after subtracting 687 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Let's proceed to step 10:
687 goes into 4630 6 times with a remainder of 508.
Write down 6 as next digit of the result. 
Result so far: 113448.16
If we subtract 4122 from 4630, we get 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

On to step 11:
687 can be fit into 5080 7 times, resulting in a remainder of 271.
Put 7 as the next digit of the answer. 
Result so far: 113448.167
If we subtract 4809 from 5080, we get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

On to step 12:
2710 divided by 687 is 3 with a remainder of 649.
Put 3 as the next digit of the answer. 
Result so far: 113448.1673
Subtracting 2061 from 2710 leaves us with 649.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6490, and continue the process.

On to step 13:
687 goes into 6490 9 times with a remainder of 307.
Write down 9 as next digit of the result. 
Result so far: 113448.16739
If we take 6183 away from 6490, we end up with 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Step 14:
When dividing 3070 by 687, we get 4 with a remainder of 322.
The next digit of our result is 4. 
Result so far: 113448.167394
Subtracting 2748 from 3070 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Step 15:
If we divide 3220 by 687, we get 4 and a remainder of 472.
Put 4 as the next digit of the answer. 
Result so far: 113448.1673944
Subtract 2748 from 3220 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

In conclusion, the division gives 113448.1673944 with a balance of 4.72e-06.
