We divide 77831979 by 629
We want to divide 77831979 by 629.

Going ahead to step 1:
When dividing 7 by 629, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 629

On to step 2:
629 goes into 77 0 times with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Include the next digit (8) from the dividend after 77, then repeat: 778 / 629

Advancing to step 3:
The number 629 fits into 778 1 times, leaving a remainder of 149.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 629 from 778 to get 149.
Include the next digit (3) from the dividend after 149, then repeat: 1493 / 629

Moving on to step 4:
If we divide 1493 by 629, we get 2 and a remainder of 235.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 1258 from 1493, we get 235.
Append the next digit (1) from the dividend to 235 and continue with: 2351 / 629

Step 5:
629 goes into 2351 3 times with a remainder of 464.
Put 3 as the next digit of the answer. 
Result so far: 123.0
If we subtract 1887 from 2351, we get 464.
Bring next digit (9) of the dividend behind the 464 and repeat the process: 4649 / 629

Going ahead to step 6:
629 goes into 4649 7 times with a remainder of 246.
The number 7 becomes the next digit in our result. 
Result so far: 1237.0
Deduct 4403 from 4649 and we're left with 246.
Fetch the next digit (7) from the dividend, attach it to 246 and continue: 2467 / 629

Moving on to step 7:
If we divide 2467 by 629, we get 3 and a remainder of 580.
Record the quotient 3 as the next digit in the result. 
Result so far: 12373.0
Deduct 1887 from 2467 and we're left with 580.
Take the next digit (9) from the dividend and append it to 580, then repeat: 5809 / 629

Let's proceed to step 8:
The number 629 fits into 5809 9 times, leaving a remainder of 148.
The next digit of our result is 9. 
Result so far: 123739.0
If we subtract 5661 from 5809, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 9:
When dividing 1480 by 629, we get 2 with a remainder of 222.
Record the quotient 2 as the next digit in the result. 
Result so far: 123739.2
If we take 1258 away from 1480, we end up with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Let's proceed to step 10:
629 goes into 2220 3 times with a remainder of 333.
Write down 3 as next digit of the result. 
Result so far: 123739.23
If we take 1887 away from 2220, we end up with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Going ahead to step 11:
If we divide 3330 by 629, we get 5 and a remainder of 185.
Record the quotient 5 as the next digit in the result. 
Result so far: 123739.235
If we subtract 3145 from 3330, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Going ahead to step 12:
629 goes into 1850 2 times with a remainder of 592.
The next digit of our result is 2. 
Result so far: 123739.2352
Subtract 1258 from 1850 to get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Going ahead to step 13:
629 goes into 5920 9 times with a remainder of 259.
Put 9 as the next digit of the answer. 
Result so far: 123739.23529
If we take 5661 away from 5920, we end up with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Moving on to step 14:
If we divide 2590 by 629, we get 4 and a remainder of 74.
The number 4 becomes the next digit in our result. 
Result so far: 123739.235294
If we subtract 2516 from 2590, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 15:
If we divide 740 by 629, we get 1 and a remainder of 111.
Record the quotient 1 as the next digit in the result. 
Result so far: 123739.2352941
If we subtract 629 from 740, we get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Advancing to step 16:
The number 629 fits into 1110 1 times, leaving a remainder of 481.
The next digit of our result is 1. 
Result so far: 123739.23529411
If we subtract 629 from 1110, we get 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

In conclusion, the division gives 123739.23529411 with a balance of 4.81e-07.
