We look at the division of 90858374 by 198 
We want to figure out the number of times 90858374 can be divided by 198.

Step 1:
198 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 198

On to step 2:
90 divided by 198 is 0 with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Include the next digit (8) from the dividend after 90, then repeat: 908 / 198

Advancing to step 3:
198 goes into 908 4 times with a remainder of 116.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 792 from 908, we get 116.
Append the next digit (5) from the dividend to 116 and continue with: 1165 / 198

Step 4:
1165 divided by 198 is 5 with a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 45.0
Subtract 990 from 1165 to get 175.
Take the next digit (8) from the dividend and append it to 175, then repeat: 1758 / 198

Step 5:
198 goes into 1758 8 times with a remainder of 174.
The next digit of our result is 8. 
Result so far: 458.0
If we take 1584 away from 1758, we end up with 174.
Include the next digit (3) from the dividend after 174, then repeat: 1743 / 198

Advancing to step 6:
198 goes into 1743 8 times with a remainder of 159.
Write down 8 as next digit of the result. 
Result so far: 4588.0
Subtracting 1584 from 1743 leaves us with 159.
Fetch the next digit (7) from the dividend, attach it to 159 and continue: 1597 / 198

Step 7:
1597 divided by 198 is 8 with a remainder of 13.
The next digit of our result is 8. 
Result so far: 45888.0
The remainder is 13 after subtracting 1584 from 1597.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 198

Step 8:
The number 198 fits into 134 0 times, leaving a remainder of 134.
Record the quotient 0 as the next digit in the result. 
Result so far: 458880.0
If we take 0 away from 134, we end up with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Step 9:
If we divide 1340 by 198, we get 6 and a remainder of 152.
Put 6 as the next digit of the answer. 
Result so far: 458880.6
If we subtract 1188 from 1340, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 10:
If we divide 1520 by 198, we get 7 and a remainder of 134.
Put 7 as the next digit of the answer. 
Result so far: 458880.67
Deduct 1386 from 1520 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 11:
198 goes into 1340 6 times with a remainder of 152.
The number 6 becomes the next digit in our result. 
Result so far: 458880.676
If we take 1188 away from 1340, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 12:
198 goes into 1520 7 times with a remainder of 134.
The next digit of our result is 7. 
Result so far: 458880.6767
Deduct 1386 from 1520 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 13:
If we divide 1340 by 198, we get 6 and a remainder of 152.
Record the quotient 6 as the next digit in the result. 
Result so far: 458880.67676
If we subtract 1188 from 1340, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 14:
If we divide 1520 by 198, we get 7 and a remainder of 134.
The next digit of our result is 7. 
Result so far: 458880.676767
Deduct 1386 from 1520 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Let's proceed to step 15:
198 goes into 1340 6 times with a remainder of 152.
Put 6 as the next digit of the answer. 
Result so far: 458880.6767676
The remainder is 152 after subtracting 1188 from 1340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 16:
198 can be fit into 1520 7 times, resulting in a remainder of 134.
Write down 7 as next digit of the result. 
Result so far: 458880.67676767
Deduct 1386 from 1520 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

The final outcome is 458880.67676767, with a leftover of 1.34e-07.
