We're dividing 85515150 by 189 
We want to divide 85515150 by 189.

Going ahead to step 1:
If we divide 8 by 189, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 189

On to step 2:
When dividing 85 by 189, we get 0 with a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Grab the next digit (5) from the dividend, add it to 85, then carry on: 855 / 189

Going ahead to step 3:
855 divided by 189 is 4 with a remainder of 99.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 756 from 855 leaves us with 99.
Append the next digit (1) from the dividend to 99 and continue with: 991 / 189

Let's proceed to step 4:
189 goes into 991 5 times with a remainder of 46.
The next digit of our result is 5. 
Result so far: 45.0
Deduct 945 from 991 and we're left with 46.
Grab the next digit (5) from the dividend, add it to 46, then carry on: 465 / 189

Let's proceed to step 5:
465 divided by 189 is 2 with a remainder of 87.
Write down 2 as next digit of the result. 
Result so far: 452.0
If we take 378 away from 465, we end up with 87.
Include the next digit (1) from the dividend after 87, then repeat: 871 / 189

Moving on to step 6:
When dividing 871 by 189, we get 4 with a remainder of 115.
Record the quotient 4 as the next digit in the result. 
Result so far: 4524.0
Subtracting 756 from 871 leaves us with 115.
Append the next digit (5) from the dividend to 115 and continue with: 1155 / 189

Step 7:
When dividing 1155 by 189, we get 6 with a remainder of 21.
The number 6 becomes the next digit in our result. 
Result so far: 45246.0
If we subtract 1134 from 1155, we get 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 189

Advancing to step 8:
210 divided by 189 is 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 452461.0
If we take 189 away from 210, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 9:
When dividing 210 by 189, we get 1 with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 452461.1
Subtracting 189 from 210 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 10:
When dividing 210 by 189, we get 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 452461.11
Subtracting 189 from 210 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final outcome is 452461.11, with a leftover of 0.021.
