198201 divided by 90 
Let's see how many times 90 fits into 198201.

Let's proceed to step 1:
The number 90 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 90

Let's proceed to step 2:
The number 90 fits into 19 0 times, leaving a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 90

Going ahead to step 3:
198 divided by 90 is 2 with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 180 from 198 to get 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 90

Step 4:
182 divided by 90 is 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we subtract 180 from 182, we get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 90

On to step 5:
When dividing 20 by 90, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 220.0
The remainder is 20 after subtracting 0 from 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 90

Step 6:
90 goes into 201 2 times with a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 2202.0
Deduct 180 from 201 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
90 can be fit into 210 2 times, resulting in a remainder of 30.
The next digit of our result is 2. 
Result so far: 2202.2
The remainder is 30 after subtracting 180 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
90 goes into 300 3 times with a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 2202.23
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
The number 90 fits into 300 3 times, leaving a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 2202.233
Deduct 270 from 300 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 2202.233 with a remaining 0.003.
