We look at the division of 72399417 by 79 
We want to figure out the number of times 72399417 can be divided by 79.

Let's proceed to step 1:
79 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
If we subtract 0 from 7, we get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 79

Advancing to step 2:
79 goes into 72 0 times with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Append the next digit (3) from the dividend to 72 and continue with: 723 / 79

Let's proceed to step 3:
If we divide 723 by 79, we get 9 and a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 711 from 723 and we're left with 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 79

Moving on to step 4:
129 divided by 79 is 1 with a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
Subtract 79 from 129 to get 50.
Append the next digit (9) from the dividend to 50 and continue with: 509 / 79

On to step 5:
509 divided by 79 is 6 with a remainder of 35.
Record the quotient 6 as the next digit in the result. 
Result so far: 916.0
The remainder is 35 after subtracting 474 from 509.
Append the next digit (4) from the dividend to 35 and continue with: 354 / 79

Step 6:
79 can be fit into 354 4 times, resulting in a remainder of 38.
The next digit of our result is 4. 
Result so far: 9164.0
If we subtract 316 from 354, we get 38.
Take the next digit (1) from the dividend and append it to 38, then repeat: 381 / 79

Advancing to step 7:
79 goes into 381 4 times with a remainder of 65.
The number 4 becomes the next digit in our result. 
Result so far: 91644.0
Subtract 316 from 381 to get 65.
Fetch the next digit (7) from the dividend, attach it to 65 and continue: 657 / 79

On to step 8:
The number 79 fits into 657 8 times, leaving a remainder of 25.
Record the quotient 8 as the next digit in the result. 
Result so far: 916448.0
Subtracting 632 from 657 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 9:
79 can be fit into 250 3 times, resulting in a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 916448.3
Deduct 237 from 250 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 10:
The number 79 fits into 130 1 times, leaving a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 916448.31
If we subtract 79 from 130, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 11:
79 can be fit into 510 6 times, resulting in a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 916448.316
If we take 474 away from 510, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 12:
If we divide 360 by 79, we get 4 and a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 916448.3164
Subtracting 316 from 360 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 13:
If we divide 440 by 79, we get 5 and a remainder of 45.
The next digit of our result is 5. 
Result so far: 916448.31645
If we take 395 away from 440, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 14:
450 divided by 79 is 5 with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 916448.316455
Deduct 395 from 450 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The quotient of the division is 916448.316455, and the remainder is 5.5e-06.
