Let's divide 721663 by 79
We want to figure out the number of times 721663 can be divided by 79.

Advancing to step 1:
When dividing 7 by 79, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 79

On to step 2:
The number 79 fits into 72 0 times, leaving a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Grab the next digit (1) from the dividend, add it to 72, then carry on: 721 / 79

Let's proceed to step 3:
The number 79 fits into 721 9 times, leaving a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 711 from 721, we get 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 79

Step 4:
When dividing 106 by 79, we get 1 with a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
Subtracting 79 from 106 leaves us with 27.
Fetch the next digit (6) from the dividend, attach it to 27 and continue: 276 / 79

Let's proceed to step 5:
79 goes into 276 3 times with a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 913.0
Subtract 237 from 276 to get 39.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 79

Going ahead to step 6:
If we divide 393 by 79, we get 4 and a remainder of 77.
The next digit of our result is 4. 
Result so far: 9134.0
Deduct 316 from 393 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 7:
If we divide 770 by 79, we get 9 and a remainder of 59.
Record the quotient 9 as the next digit in the result. 
Result so far: 9134.9
Subtract 711 from 770 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 8:
When dividing 590 by 79, we get 7 with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 9134.97
If we subtract 553 from 590, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 9:
When dividing 370 by 79, we get 4 with a remainder of 54.
Write down 4 as next digit of the result. 
Result so far: 9134.974
Deduct 316 from 370 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 10:
If we divide 540 by 79, we get 6 and a remainder of 66.
Record the quotient 6 as the next digit in the result. 
Result so far: 9134.9746
If we take 474 away from 540, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 11:
The number 79 fits into 660 8 times, leaving a remainder of 28.
The next digit of our result is 8. 
Result so far: 9134.97468
Subtracting 632 from 660 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 12:
When dividing 280 by 79, we get 3 with a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 9134.974683
If we subtract 237 from 280, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 13:
When dividing 430 by 79, we get 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 9134.9746835
Subtract 395 from 430 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 14:
When dividing 350 by 79, we get 4 with a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 9134.97468354
Deduct 316 from 350 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

In conclusion, the division gives 9134.97468354 with a balance of 3.4e-08.
