We divide 391124 by 5
We want to figure out the number of times 391124 can be divided by 5.

Advancing to step 1:
The number 5 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 5

Going ahead to step 2:
If we divide 39 by 5, we get 7 and a remainder of 4.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 35 from 39 to get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 5

Going ahead to step 3:
The number 5 fits into 41 8 times, leaving a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 78.0
If we take 40 away from 41, we end up with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 5

Going ahead to step 4:
If we divide 11 by 5, we get 2 and a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 782.0
If we subtract 10 from 11, we get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 5

Moving on to step 5:
If we divide 12 by 5, we get 2 and a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 7822.0
The remainder is 2 after subtracting 10 from 12.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 5

Step 6:
5 goes into 24 4 times with a remainder of 4.
The next digit of our result is 4. 
Result so far: 78224.0
Deduct 20 from 24 and we're left 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.

Step 7:
5 can be fit into 40 8 times, resulting in a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 78224.8
Subtract 40 from 40 to get 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 8:
The number 5 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 78224.8
If we take 0 away from 0, we end up 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 9:
The number 5 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 78224.8
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 78224.8 and a remainder of 0.0.
