We look at the division of 425116 by 90 
We want to divide 425116 by 90.

On to step 1:
If we divide 4 by 90, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 90

On to step 2:
When dividing 42 by 90, we get 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Include the next digit (5) from the dividend after 42, then repeat: 425 / 90

Advancing to step 3:
425 divided by 90 is 4 with a remainder of 65.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 360 from 425 and we're left with 65.
Append the next digit (1) from the dividend to 65 and continue with: 651 / 90

On to step 4:
If we divide 651 by 90, we get 7 and a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 47.0
Subtract 630 from 651 to get 21.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 90

Advancing to step 5:
When dividing 211 by 90, we get 2 with a remainder of 31.
Record the quotient 2 as the next digit in the result. 
Result so far: 472.0
If we subtract 180 from 211, we get 31.
Fetch the next digit (6) from the dividend, attach it to 31 and continue: 316 / 90

Moving on to step 6:
If we divide 316 by 90, we get 3 and a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 4723.0
If we subtract 270 from 316, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 7:
If we divide 460 by 90, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 4723.5
If we take 450 away from 460, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
90 can be fit into 100 1 times, resulting in a remainder of 10.
The next digit of our result is 1. 
Result so far: 4723.51
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
90 goes into 100 1 times with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 4723.511
If we subtract 90 from 100, we 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.

The quotient of the division is 4723.511, and the remainder is 0.001.
