Let's divide 90152191 by 412
Let's see how many times 412 fits into 90152191.

Moving on to step 1:
If we divide 9 by 412, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 412

Moving on to step 2:
412 goes into 90 0 times with a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Fetch the next digit (1) from the dividend, attach it to 90 and continue: 901 / 412

On to step 3:
412 can be fit into 901 2 times, resulting in a remainder of 77.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 77 after subtracting 824 from 901.
Fetch the next digit (5) from the dividend, attach it to 77 and continue: 775 / 412

Going ahead to step 4:
412 can be fit into 775 1 times, resulting in a remainder of 363.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtract 412 from 775 to get 363.
Bring next digit (2) of the dividend behind the 363 and repeat the process: 3632 / 412

Moving on to step 5:
If we divide 3632 by 412, we get 8 and a remainder of 336.
Write down 8 as next digit of the result. 
Result so far: 218.0
If we take 3296 away from 3632, we end up with 336.
Fetch the next digit (1) from the dividend, attach it to 336 and continue: 3361 / 412

Advancing to step 6:
If we divide 3361 by 412, we get 8 and a remainder of 65.
Put 8 as the next digit of the answer. 
Result so far: 2188.0
Subtract 3296 from 3361 to get 65.
Include the next digit (9) from the dividend after 65, then repeat: 659 / 412

Going ahead to step 7:
When dividing 659 by 412, we get 1 with a remainder of 247.
Put 1 as the next digit of the answer. 
Result so far: 21881.0
If we subtract 412 from 659, we get 247.
Append the next digit (1) from the dividend to 247 and continue with: 2471 / 412

Going ahead to step 8:
The number 412 fits into 2471 5 times, leaving a remainder of 411.
The number 5 becomes the next digit in our result. 
Result so far: 218815.0
Subtract 2060 from 2471 to get 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

On to step 9:
412 can be fit into 4110 9 times, resulting in a remainder of 402.
Record the quotient 9 as the next digit in the result. 
Result so far: 218815.9
If we subtract 3708 from 4110, we get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Going ahead to step 10:
The number 412 fits into 4020 9 times, leaving a remainder of 312.
Record the quotient 9 as the next digit in the result. 
Result so far: 218815.99
If we subtract 3708 from 4020, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

The final result is 218815.99 with a remainder of 0.312.
