We divide 87109911 by 4
We're looking to find how many times 4 goes into 87109911.

Going ahead to step 1:
The number 4 fits into 8 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 0 after subtracting 8 from 8.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 4

Moving on to step 2:
4 goes into 7 1 times with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
The remainder is 3 after subtracting 4 from 7.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 4

Going ahead to step 3:
The number 4 fits into 31 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
Result so far: 217.0
Deduct 28 from 31 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 4

On to step 4:
When dividing 30 by 4, we get 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 2177.0
If we subtract 28 from 30, we get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 4

Advancing to step 5:
If we divide 29 by 4, we get 7 and a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 21777.0
The remainder is 1 after subtracting 28 from 29.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 4

Let's proceed to step 6:
4 goes into 19 4 times with a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 217774.0
Subtract 16 from 19 to get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 4

Moving on to step 7:
If we divide 31 by 4, we get 7 and a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 2177747.0
If we subtract 28 from 31, we get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 4

Going ahead to step 8:
4 can be fit into 31 7 times, resulting in a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 21777477.0
Subtract 28 from 31 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
When dividing 30 by 4, we get 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 21777477.7
Subtracting 28 from 30 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.

Moving on to step 10:
4 goes into 20 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 21777477.75
If we subtract 20 from 20, 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.

On to step 11:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 21777477.75
The remainder is 0 after subtracting 0 from 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 12:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 21777477.75
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.

Our division results in 21777477.75 with a remaining 0.0.
