Let's divide 85128821 by 609
We want to divide 85128821 by 609.

On to step 1:
The number 609 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 609

Moving on to step 2:
609 goes into 85 0 times 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.
Take the next digit (1) from the dividend and append it to 85, then repeat: 851 / 609

Let's proceed to step 3:
The number 609 fits into 851 1 times, leaving a remainder of 242.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 609 from 851 to get 242.
Append the next digit (2) from the dividend to 242 and continue with: 2422 / 609

Let's proceed to step 4:
If we divide 2422 by 609, we get 3 and a remainder of 595.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 595 after subtracting 1827 from 2422.
Take the next digit (8) from the dividend and append it to 595, then repeat: 5958 / 609

Let's proceed to step 5:
5958 divided by 609 is 9 with a remainder of 477.
Record the quotient 9 as the next digit in the result. 
Result so far: 139.0
If we subtract 5481 from 5958, we get 477.
Fetch the next digit (8) from the dividend, attach it to 477 and continue: 4778 / 609

Moving on to step 6:
4778 divided by 609 is 7 with a remainder of 515.
Use 7 as the next digit of our solution. 
Result so far: 1397.0
If we subtract 4263 from 4778, we get 515.
Take the next digit (2) from the dividend and append it to 515, then repeat: 5152 / 609

Going ahead to step 7:
When dividing 5152 by 609, we get 8 with a remainder of 280.
Write down 8 as next digit of the result. 
Result so far: 13978.0
Deduct 4872 from 5152 and we're left with 280.
Take the next digit (1) from the dividend and append it to 280, then repeat: 2801 / 609

Advancing to step 8:
If we divide 2801 by 609, we get 4 and a remainder of 365.
Write down 4 as next digit of the result. 
Result so far: 139784.0
Subtract 2436 from 2801 to get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

On to step 9:
When dividing 3650 by 609, we get 5 with a remainder of 605.
Put 5 as the next digit of the answer. 
Result so far: 139784.5
The remainder is 605 after subtracting 3045 from 3650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Let's proceed to step 10:
If we divide 6050 by 609, we get 9 and a remainder of 569.
Write down 9 as next digit of the result. 
Result so far: 139784.59
Deduct 5481 from 6050 and we're left with 569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

Advancing to step 11:
5690 divided by 609 is 9 with a remainder of 209.
Record the quotient 9 as the next digit in the result. 
Result so far: 139784.599
The remainder is 209 after subtracting 5481 from 5690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

The quotient of the division is 139784.599, and the remainder is 0.0209.
