Let's divide 85257187 by 550
We want to divide 85257187 by 550.

On to step 1:
The number 550 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 550

Moving on to step 2:
When dividing 85 by 550, we get 0 with a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Grab the next digit (2) from the dividend, add it to 85, then carry on: 852 / 550

Step 3:
550 can be fit into 852 1 times, resulting in a remainder of 302.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 550 from 852 to get 302.
Take the next digit (5) from the dividend and append it to 302, then repeat: 3025 / 550

Going ahead to step 4:
550 can be fit into 3025 5 times, resulting in a remainder of 275.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 2750 from 3025 and we're left with 275.
Take the next digit (7) from the dividend and append it to 275, then repeat: 2757 / 550

On to step 5:
550 can be fit into 2757 5 times, resulting in a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 155.0
Subtract 2750 from 2757 to get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 550

Step 6:
If we divide 71 by 550, we get 0 and a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 1550.0
Subtracting 0 from 71 leaves us with 71.
Fetch the next digit (8) from the dividend, attach it to 71 and continue: 718 / 550

Going ahead to step 7:
550 can be fit into 718 1 times, resulting in a remainder of 168.
Record the quotient 1 as the next digit in the result. 
Result so far: 15501.0
The remainder is 168 after subtracting 550 from 718.
Bring next digit (7) of the dividend behind the 168 and repeat the process: 1687 / 550

On to step 8:
1687 divided by 550 is 3 with a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 155013.0
If we take 1650 away from 1687, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 9:
550 goes into 370 0 times with a remainder of 370.
Write down 0 as next digit of the result. 
Result so far: 155013.0
Deduct 0 from 370 and we're left with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Step 10:
550 goes into 3700 6 times with a remainder of 400.
Put 6 as the next digit of the answer. 
Result so far: 155013.06
The remainder is 400 after subtracting 3300 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 11:
When dividing 4000 by 550, we get 7 with a remainder of 150.
The next digit of our result is 7. 
Result so far: 155013.067
Subtracting 3850 from 4000 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 12:
If we divide 1500 by 550, we get 2 and a remainder of 400.
The next digit of our result is 2. 
Result so far: 155013.0672
If we take 1100 away from 1500, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 13:
When dividing 4000 by 550, we get 7 with a remainder of 150.
The number 7 becomes the next digit in our result. 
Result so far: 155013.06727
Subtract 3850 from 4000 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 14:
When dividing 1500 by 550, we get 2 with a remainder of 400.
Record the quotient 2 as the next digit in the result. 
Result so far: 155013.067272
The remainder is 400 after subtracting 1100 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 15:
If we divide 4000 by 550, we get 7 and a remainder of 150.
Put 7 as the next digit of the answer. 
Result so far: 155013.0672727
The remainder is 150 after subtracting 3850 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 16:
550 can be fit into 1500 2 times, resulting in a remainder of 400.
Use 2 as the next digit of our solution. 
Result so far: 155013.06727272
If we take 1100 away from 1500, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 155013.06727272 with a remainder of 4e-07.
