154117 ÷ 90 
Our goal is to divide 154117 by 90.

Let's proceed to step 1:
90 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 90

Let's proceed to step 2:
If we divide 15 by 90, we get 0 and a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 90

Let's proceed to step 3:
If we divide 154 by 90, we get 1 and a remainder of 64.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 90 from 154, we get 64.
Grab the next digit (1) from the dividend, add it to 64, then carry on: 641 / 90

Going ahead to step 4:
If we divide 641 by 90, we get 7 and a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 17.0
The remainder is 11 after subtracting 630 from 641.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 90

Let's proceed to step 5:
The number 90 fits into 111 1 times, leaving a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 171.0
Deduct 90 from 111 and we're left with 21.
Include the next digit (7) from the dividend after 21, then repeat: 217 / 90

On to step 6:
If we divide 217 by 90, we get 2 and a remainder of 37.
Write down 2 as next digit of the result. 
Result so far: 1712.0
Deduct 180 from 217 and we're left 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.

Going ahead to step 7:
When dividing 370 by 90, we get 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 1712.4
If we take 360 away from 370, 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.

On to step 8:
90 can be fit into 100 1 times, resulting in a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1712.41
Subtracting 90 from 100 leaves us 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:
If we divide 100 by 90, we get 1 and a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1712.411
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.

Our division results in 1712.411 with a remaining 0.001.
