78638695 divided by 79 
Let's see how many times 79 fits into 78638695.

Step 1:
79 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 79

On to step 2:
78 divided by 79 is 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Grab the next digit (6) from the dividend, add it to 78, then carry on: 786 / 79

Moving on to step 3:
If we divide 786 by 79, we get 9 and a remainder of 75.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 711 from 786, we get 75.
Append the next digit (3) from the dividend to 75 and continue with: 753 / 79

Going ahead to step 4:
If we divide 753 by 79, we get 9 and a remainder of 42.
Put 9 as the next digit of the answer. 
Result so far: 99.0
The remainder is 42 after subtracting 711 from 753.
Include the next digit (8) from the dividend after 42, then repeat: 428 / 79

On to step 5:
79 can be fit into 428 5 times, resulting in a remainder of 33.
Put 5 as the next digit of the answer. 
Result so far: 995.0
Deduct 395 from 428 and we're left with 33.
Include the next digit (6) from the dividend after 33, then repeat: 336 / 79

Going ahead to step 6:
79 goes into 336 4 times with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 9954.0
If we subtract 316 from 336, we get 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 79

Advancing to step 7:
79 goes into 209 2 times with a remainder of 51.
The next digit of our result is 2. 
Result so far: 99542.0
The remainder is 51 after subtracting 158 from 209.
Grab the next digit (5) from the dividend, add it to 51, then carry on: 515 / 79

Going ahead to step 8:
When dividing 515 by 79, we get 6 with a remainder of 41.
Write down 6 as next digit of the result. 
Result so far: 995426.0
Subtract 474 from 515 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 9:
If we divide 410 by 79, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 995426.5
Subtract 395 from 410 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 10:
The number 79 fits into 150 1 times, leaving a remainder of 71.
Write down 1 as next digit of the result. 
Result so far: 995426.51
Subtract 79 from 150 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 11:
79 can be fit into 710 8 times, resulting in a remainder of 78.
The number 8 becomes the next digit in our result. 
Result so far: 995426.518
If we subtract 632 from 710, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 12:
79 can be fit into 780 9 times, resulting in a remainder of 69.
The next digit of our result is 9. 
Result so far: 995426.5189
Deduct 711 from 780 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 13:
When dividing 690 by 79, we get 8 with a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 995426.51898
Subtract 632 from 690 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 14:
When dividing 580 by 79, we get 7 with a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 995426.518987
Deduct 553 from 580 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 15:
If we divide 270 by 79, we get 3 and a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 995426.5189873
The remainder is 33 after subtracting 237 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 16:
When dividing 330 by 79, we get 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 995426.51898734
Subtract 316 from 330 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 995426.51898734 with a remainder of 1.4e-08.
