Let's divide 90109821 by 199
Let's see how many times 199 fits into 90109821.

On to step 1:
199 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 199

Advancing to step 2:
90 divided by 199 is 0 with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Grab the next digit (1) from the dividend, add it to 90, then carry on: 901 / 199

Let's proceed to step 3:
If we divide 901 by 199, we get 4 and a remainder of 105.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 796 from 901, we get 105.
Grab the next digit (0) from the dividend, add it to 105, then carry on: 1050 / 199

On to step 4:
The number 199 fits into 1050 5 times, leaving a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
If we subtract 995 from 1050, we get 55.
Include the next digit (9) from the dividend after 55, then repeat: 559 / 199

Moving on to step 5:
199 can be fit into 559 2 times, resulting in a remainder of 161.
The next digit of our result is 2. 
Result so far: 452.0
Subtract 398 from 559 to get 161.
Grab the next digit (8) from the dividend, add it to 161, then carry on: 1618 / 199

Advancing to step 6:
When dividing 1618 by 199, we get 8 with a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 4528.0
If we subtract 1592 from 1618, we get 26.
Fetch the next digit (2) from the dividend, attach it to 26 and continue: 262 / 199

On to step 7:
199 goes into 262 1 times with a remainder of 63.
The number 1 becomes the next digit in our result. 
Result so far: 45281.0
Subtract 199 from 262 to get 63.
Bring next digit (1) of the dividend behind the 63 and repeat the process: 631 / 199

On to step 8:
631 divided by 199 is 3 with a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 452813.0
The remainder is 34 after subtracting 597 from 631.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 9:
199 goes into 340 1 times with a remainder of 141.
The number 1 becomes the next digit in our result. 
Result so far: 452813.1
The remainder is 141 after subtracting 199 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Advancing to step 10:
1410 divided by 199 is 7 with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 452813.17
If we take 1393 away from 1410, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 11:
If we divide 170 by 199, we get 0 and a remainder of 170.
Write down 0 as next digit of the result. 
Result so far: 452813.17
If we subtract 0 from 170, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 12:
1700 divided by 199 is 8 with a remainder of 108.
Record the quotient 8 as the next digit in the result. 
Result so far: 452813.1708
Subtract 1592 from 1700 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 13:
When dividing 1080 by 199, we get 5 with a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 452813.17085
If we subtract 995 from 1080, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 14:
If we divide 850 by 199, we get 4 and a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 452813.170854
Subtract 796 from 850 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 15:
199 can be fit into 540 2 times, resulting in a remainder of 142.
Use 2 as the next digit of our solution. 
Result so far: 452813.1708542
If we subtract 398 from 540, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 16:
The number 199 fits into 1420 7 times, leaving a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 452813.17085427
The remainder is 27 after subtracting 1393 from 1420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final outcome is 452813.17085427, with a leftover of 2.7e-08.
