We divide 859198 by 90
We're looking to find how many times 90 goes into 859198.

Let's proceed to step 1:
When dividing 8 by 90, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 90

Advancing to step 2:
85 divided by 90 is 0 with a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Append the next digit (9) from the dividend to 85 and continue with: 859 / 90

Let's proceed to step 3:
90 can be fit into 859 9 times, resulting in a remainder of 49.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 810 from 859 leaves us with 49.
Fetch the next digit (1) from the dividend, attach it to 49 and continue: 491 / 90

Let's proceed to step 4:
When dividing 491 by 90, we get 5 with a remainder of 41.
Put 5 as the next digit of the answer. 
Result so far: 95.0
If we subtract 450 from 491, we get 41.
Append the next digit (9) from the dividend to 41 and continue with: 419 / 90

Going ahead to step 5:
If we divide 419 by 90, we get 4 and a remainder of 59.
Put 4 as the next digit of the answer. 
Result so far: 954.0
The remainder is 59 after subtracting 360 from 419.
Take the next digit (8) from the dividend and append it to 59, then repeat: 598 / 90

Moving on to step 6:
90 can be fit into 598 6 times, resulting in a remainder of 58.
Use 6 as the next digit of our solution. 
Result so far: 9546.0
The remainder is 58 after subtracting 540 from 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 7:
90 goes into 580 6 times with a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 9546.6
The remainder is 40 after subtracting 540 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
If we divide 400 by 90, we get 4 and a remainder of 40.
The next digit of our result is 4. 
Result so far: 9546.64
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
90 goes into 400 4 times with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 9546.644
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 9546.644, and the remainder is 0.004.
