Let's divide 166898 by 90
We want to figure out the number of times 166898 can be divided by 90.

Let's proceed to step 1:
If we divide 1 by 90, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 90

Going ahead to step 2:
16 divided by 90 is 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 90

Moving on to step 3:
90 can be fit into 166 1 times, resulting in a remainder of 76.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 90 from 166 leaves us with 76.
Bring next digit (8) of the dividend behind the 76 and repeat the process: 768 / 90

Going ahead to step 4:
The number 90 fits into 768 8 times, leaving a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtract 720 from 768 to get 48.
Fetch the next digit (9) from the dividend, attach it to 48 and continue: 489 / 90

Going ahead to step 5:
When dividing 489 by 90, we get 5 with a remainder of 39.
The number 5 becomes the next digit in our result. 
Result so far: 185.0
The remainder is 39 after subtracting 450 from 489.
Append the next digit (8) from the dividend to 39 and continue with: 398 / 90

Going ahead to step 6:
90 goes into 398 4 times with a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 1854.0
Subtracting 360 from 398 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 7:
The number 90 fits into 380 4 times, leaving a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 1854.4
Deduct 360 from 380 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
200 divided by 90 is 2 with a remainder of 20.
The next digit of our result is 2. 
Result so far: 1854.42
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
90 goes into 200 2 times with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 1854.422
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 1854.422 with a remaining 0.002.
