Let's divide 91285558 by 4
Let's see how many times 4 fits into 91285558.

Going ahead to step 1:
9 divided by 4 is 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 8 from 9 leaves us with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 4

Going ahead to step 2:
When dividing 11 by 4, we get 2 with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we take 8 away from 11, we end up with 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 4

On to step 3:
If we divide 32 by 4, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 228.0
Deduct 32 from 32 and we're left with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 4

Moving on to step 4:
The number 4 fits into 8 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2282.0
If we subtract 8 from 8, we get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 4

Let's proceed to step 5:
4 can be fit into 5 1 times, resulting in a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 22821.0
Subtract 4 from 5 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 4

Step 6:
4 can be fit into 15 3 times, resulting in a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 228213.0
Subtracting 12 from 15 leaves us with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 4

Advancing to step 7:
4 can be fit into 35 8 times, resulting in a remainder of 3.
The next digit of our result is 8. 
Result so far: 2282138.0
Subtract 32 from 35 to get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 4

Let's proceed to step 8:
If we divide 38 by 4, we get 9 and a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 22821389.0
Subtract 36 from 38 to get 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:
20 divided by 4 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 22821389.5
Subtract 20 from 20 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.

Advancing to step 10:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 22821389.5
Deduct 0 from 0 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.

Let's proceed to step 11:
4 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 22821389.5
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.

Our division results in 22821389.5 with a remaining 0.0.
