We look at the division of 90572971 by 204 
We want to divide 90572971 by 204.

Going ahead to step 1:
9 divided by 204 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 204

Step 2:
90 divided by 204 is 0 with a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Include the next digit (5) from the dividend after 90, then repeat: 905 / 204

On to step 3:
When dividing 905 by 204, we get 4 with a remainder of 89.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 816 from 905 leaves us with 89.
Include the next digit (7) from the dividend after 89, then repeat: 897 / 204

Advancing to step 4:
When dividing 897 by 204, we get 4 with a remainder of 81.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
The remainder is 81 after subtracting 816 from 897.
Include the next digit (2) from the dividend after 81, then repeat: 812 / 204

Moving on to step 5:
204 can be fit into 812 3 times, resulting in a remainder of 200.
Put 3 as the next digit of the answer. 
Result so far: 443.0
Subtract 612 from 812 to get 200.
Grab the next digit (9) from the dividend, add it to 200, then carry on: 2009 / 204

Step 6:
If we divide 2009 by 204, we get 9 and a remainder of 173.
Record the quotient 9 as the next digit in the result. 
Result so far: 4439.0
The remainder is 173 after subtracting 1836 from 2009.
Append the next digit (7) from the dividend to 173 and continue with: 1737 / 204

On to step 7:
204 can be fit into 1737 8 times, resulting in a remainder of 105.
Use 8 as the next digit of our solution. 
Result so far: 44398.0
If we take 1632 away from 1737, we end up with 105.
Take the next digit (1) from the dividend and append it to 105, then repeat: 1051 / 204

Step 8:
204 can be fit into 1051 5 times, resulting in a remainder of 31.
The next digit of our result is 5. 
Result so far: 443985.0
The remainder is 31 after subtracting 1020 from 1051.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 9:
When dividing 310 by 204, we get 1 with a remainder of 106.
Write down 1 as next digit of the result. 
Result so far: 443985.1
If we subtract 204 from 310, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 10:
When dividing 1060 by 204, we get 5 with a remainder of 40.
The next digit of our result is 5. 
Result so far: 443985.15
Subtract 1020 from 1060 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
400 divided by 204 is 1 with a remainder of 196.
Use 1 as the next digit of our solution. 
Result so far: 443985.151
Deduct 204 from 400 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Advancing to step 12:
When dividing 1960 by 204, we get 9 with a remainder of 124.
Write down 9 as next digit of the result. 
Result so far: 443985.1519
If we subtract 1836 from 1960, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Let's proceed to step 13:
204 can be fit into 1240 6 times, resulting in a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 443985.15196
The remainder is 16 after subtracting 1224 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
160 divided by 204 is 0 with a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 443985.15196
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 15:
When dividing 1600 by 204, we get 7 with a remainder of 172.
Write down 7 as next digit of the result. 
Result so far: 443985.1519607
Subtracting 1428 from 1600 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Going ahead to step 16:
When dividing 1720 by 204, we get 8 with a remainder of 88.
Put 8 as the next digit of the answer. 
Result so far: 443985.15196078
Deduct 1632 from 1720 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

After the division, we end up with 443985.15196078 and a remainder of 8.8e-08.
