52987907 ÷ 5 
We want to figure out the number of times 52987907 can be divided by 5.

Advancing to step 1:
5 goes into 5 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 5 from 5, we get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 5

Step 2:
5 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 5

Going ahead to step 3:
When dividing 29 by 5, we get 5 with a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 105.0
Deduct 25 from 29 and we're left with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 5

On to step 4:
The number 5 fits into 48 9 times, leaving a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 1059.0
If we take 45 away from 48, we end up with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 5

Advancing to step 5:
If we divide 37 by 5, we get 7 and a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 10597.0
Deduct 35 from 37 and we're left with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 5

Going ahead to step 6:
When dividing 29 by 5, we get 5 with a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 105975.0
If we subtract 25 from 29, we get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 5

Let's proceed to step 7:
When dividing 40 by 5, we get 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 1059758.0
Subtracting 40 from 40 leaves us with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 5

On to step 8:
5 can be fit into 7 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 10597581.0
Subtracting 5 from 7 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
5 goes into 20 4 times with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 10597581.4
If we take 20 away from 20, 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.

Advancing to step 10:
If we divide 0 by 5, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10597581.4
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.

Going ahead to step 11:
If we divide 0 by 5, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10597581.4
Subtract 0 from 0 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.

Our division results in 10597581.4 with a remaining 0.0.
