We look at the division of 91987152 by 204 
We want to divide 91987152 by 204.

Advancing to step 1:
204 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 204

Step 2:
91 divided by 204 is 0 with a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Bring next digit (9) of the dividend behind the 91 and repeat the process: 919 / 204

Step 3:
When dividing 919 by 204, we get 4 with a remainder of 103.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 816 away from 919, we end up with 103.
Bring next digit (8) of the dividend behind the 103 and repeat the process: 1038 / 204

Advancing to step 4:
When dividing 1038 by 204, we get 5 with a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
Deduct 1020 from 1038 and we're left with 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 204

Going ahead to step 5:
187 divided by 204 is 0 with a remainder of 187.
Use 0 as the next digit of our solution. 
Result so far: 450.0
Subtracting 0 from 187 leaves us with 187.
Append the next digit (1) from the dividend to 187 and continue with: 1871 / 204

Advancing to step 6:
When dividing 1871 by 204, we get 9 with a remainder of 35.
The next digit of our result is 9. 
Result so far: 4509.0
Subtract 1836 from 1871 to get 35.
Grab the next digit (5) from the dividend, add it to 35, then carry on: 355 / 204

Going ahead to step 7:
If we divide 355 by 204, we get 1 and a remainder of 151.
Use 1 as the next digit of our solution. 
Result so far: 45091.0
Subtracting 204 from 355 leaves us with 151.
Append the next digit (2) from the dividend to 151 and continue with: 1512 / 204

On to step 8:
204 can be fit into 1512 7 times, resulting in a remainder of 84.
Put 7 as the next digit of the answer. 
Result so far: 450917.0
If we take 1428 away from 1512, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 9:
840 divided by 204 is 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 450917.4
Deduct 816 from 840 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
204 can be fit into 240 1 times, resulting in a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 450917.41
Subtracting 204 from 240 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 11:
If we divide 360 by 204, we get 1 and a remainder of 156.
Record the quotient 1 as the next digit in the result. 
Result so far: 450917.411
If we take 204 away from 360, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

The quotient of the division is 450917.411, and the remainder is 0.0156.
