We look at the division of 401089 by 85 
We want to divide 401089 by 85.

Step 1:
When dividing 4 by 85, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 85

Going ahead to step 2:
The number 85 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Take the next digit (1) from the dividend and append it to 40, then repeat: 401 / 85

On to step 3:
85 can be fit into 401 4 times, resulting in a remainder of 61.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 340 away from 401, we end up with 61.
Include the next digit (0) from the dividend after 61, then repeat: 610 / 85

Step 4:
85 can be fit into 610 7 times, resulting in a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
If we subtract 595 from 610, we get 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 85

On to step 5:
158 divided by 85 is 1 with a remainder of 73.
Write down 1 as next digit of the result. 
Result so far: 471.0
Subtract 85 from 158 to get 73.
Append the next digit (9) from the dividend to 73 and continue with: 739 / 85

Going ahead to step 6:
739 divided by 85 is 8 with a remainder of 59.
The number 8 becomes the next digit in our result. 
Result so far: 4718.0
The remainder is 59 after subtracting 680 from 739.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 7:
When dividing 590 by 85, we get 6 with a remainder of 80.
Put 6 as the next digit of the answer. 
Result so far: 4718.6
Subtracting 510 from 590 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 8:
85 can be fit into 800 9 times, resulting in a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 4718.69
If we subtract 765 from 800, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 9:
When dividing 350 by 85, we get 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 4718.694
Subtract 340 from 350 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
85 goes into 100 1 times with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 4718.6941
Deduct 85 from 100 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
85 goes into 150 1 times with a remainder of 65.
The next digit of our result is 1. 
Result so far: 4718.69411
If we subtract 85 from 150, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final outcome is 4718.69411, with a leftover of 6.5e-05.
