We divide 77990799 by 939
We want to figure out the number of times 77990799 can be divided by 939.

Advancing to step 1:
939 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 939

Going ahead to step 2:
When dividing 77 by 939, we get 0 with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Bring next digit (9) of the dividend behind the 77 and repeat the process: 779 / 939

Step 3:
939 goes into 779 0 times with a remainder of 779.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 779, we end up with 779.
Fetch the next digit (9) from the dividend, attach it to 779 and continue: 7799 / 939

On to step 4:
939 can be fit into 7799 8 times, resulting in a remainder of 287.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 7512 from 7799, we get 287.
Take the next digit (0) from the dividend and append it to 287, then repeat: 2870 / 939

Advancing to step 5:
939 goes into 2870 3 times with a remainder of 53.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
Subtract 2817 from 2870 to get 53.
Take the next digit (7) from the dividend and append it to 53, then repeat: 537 / 939

Let's proceed to step 6:
If we divide 537 by 939, we get 0 and a remainder of 537.
Record the quotient 0 as the next digit in the result. 
Result so far: 830.0
If we take 0 away from 537, we end up with 537.
Fetch the next digit (9) from the dividend, attach it to 537 and continue: 5379 / 939

On to step 7:
When dividing 5379 by 939, we get 5 with a remainder of 684.
Put 5 as the next digit of the answer. 
Result so far: 8305.0
Subtract 4695 from 5379 to get 684.
Include the next digit (9) from the dividend after 684, then repeat: 6849 / 939

Moving on to step 8:
6849 divided by 939 is 7 with a remainder of 276.
Record the quotient 7 as the next digit in the result. 
Result so far: 83057.0
The remainder is 276 after subtracting 6573 from 6849.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Advancing to step 9:
939 goes into 2760 2 times with a remainder of 882.
The number 2 becomes the next digit in our result. 
Result so far: 83057.2
Deduct 1878 from 2760 and we're left with 882.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8820, and continue the process.

On to step 10:
The number 939 fits into 8820 9 times, leaving a remainder of 369.
Write down 9 as next digit of the result. 
Result so far: 83057.29
The remainder is 369 after subtracting 8451 from 8820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Step 11:
939 goes into 3690 3 times with a remainder of 873.
Write down 3 as next digit of the result. 
Result so far: 83057.293
The remainder is 873 after subtracting 2817 from 3690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8730, and continue the process.

On to step 12:
939 goes into 8730 9 times with a remainder of 279.
Put 9 as the next digit of the answer. 
Result so far: 83057.2939
Subtracting 8451 from 8730 leaves us with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Advancing to step 13:
When dividing 2790 by 939, we get 2 with a remainder of 912.
The number 2 becomes the next digit in our result. 
Result so far: 83057.29392
Subtract 1878 from 2790 to get 912.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9120, and continue the process.

Going ahead to step 14:
939 can be fit into 9120 9 times, resulting in a remainder of 669.
Record the quotient 9 as the next digit in the result. 
Result so far: 83057.293929
Deduct 8451 from 9120 and we're left with 669.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6690, and continue the process.

Going ahead to step 15:
The number 939 fits into 6690 7 times, leaving a remainder of 117.
Use 7 as the next digit of our solution. 
Result so far: 83057.2939297
The remainder is 117 after subtracting 6573 from 6690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Step 16:
When dividing 1170 by 939, we get 1 with a remainder of 231.
Write down 1 as next digit of the result. 
Result so far: 83057.29392971
The remainder is 231 after subtracting 939 from 1170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

The quotient of the division is 83057.29392971, and the remainder is 2.31e-07.
