We look at the division of 91714239 by 5 
We want to figure out the number of times 91714239 can be divided by 5.

On to step 1:
If we divide 9 by 5, we get 1 and a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
If we take 5 away from 9, we end up with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 5

On to step 2:
If we divide 41 by 5, we get 8 and a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 18.0
The remainder is 1 after subtracting 40 from 41.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 5

Advancing to step 3:
When dividing 17 by 5, we get 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 183.0
Subtract 15 from 17 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 5

Going ahead to step 4:
5 goes into 21 4 times with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 1834.0
Subtracting 20 from 21 leaves us with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 5

Advancing to step 5:
5 goes into 14 2 times with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 18342.0
If we take 10 away from 14, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 5

Going ahead to step 6:
5 goes into 42 8 times with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 183428.0
The remainder is 2 after subtracting 40 from 42.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 5

Moving on to step 7:
23 divided by 5 is 4 with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 1834284.0
Subtracting 20 from 23 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 5

Advancing to step 8:
5 can be fit into 39 7 times, resulting in a remainder of 4.
The next digit of our result is 7. 
Result so far: 18342847.0
Subtracting 35 from 39 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
5 goes into 40 8 times with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 18342847.8
Deduct 40 from 40 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
When dividing 0 by 5, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 18342847.8
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
5 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 18342847.8
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 18342847.8 with a remaining 0.0.
