Let's divide 91989188 by 45
Let's see how many times 45 fits into 91989188.

Let's proceed to step 1:
When dividing 9 by 45, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 45

Advancing to step 2:
If we divide 91 by 45, we get 2 and a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 90 from 91 and we're left with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 45

Going ahead to step 3:
45 can be fit into 19 0 times, resulting in a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we take 0 away from 19, we end up with 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 45

Let's proceed to step 4:
When dividing 198 by 45, we get 4 with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 204.0
Deduct 180 from 198 and we're left with 18.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 45

On to step 5:
45 goes into 189 4 times with a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 2044.0
Deduct 180 from 189 and we're left with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 45

Advancing to step 6:
If we divide 91 by 45, we get 2 and a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 20442.0
Deduct 90 from 91 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 45

Going ahead to step 7:
If we divide 18 by 45, we get 0 and a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 204420.0
If we take 0 away from 18, we end up with 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 45

Moving on to step 8:
45 can be fit into 188 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 2044204.0
The remainder is 8 after subtracting 180 from 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
45 goes into 80 1 times with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 2044204.1
Subtract 45 from 80 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 10:
When dividing 350 by 45, we get 7 with a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 2044204.17
Deduct 315 from 350 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 11:
If we divide 350 by 45, we get 7 and a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 2044204.177
Subtracting 315 from 350 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 2044204.177 with a remainder of 0.0035.
