We're dividing 90643185 by 445 
We want to divide 90643185 by 445.

Moving on to step 1:
445 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
Subtracting 0 from 9 leaves us with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 445

Let's proceed to step 2:
445 can be fit into 90 0 times, resulting in a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Take the next digit (6) from the dividend and append it to 90, then repeat: 906 / 445

Advancing to step 3:
445 goes into 906 2 times with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 890 from 906, we get 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 445

On to step 4:
445 goes into 164 0 times with a remainder of 164.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Deduct 0 from 164 and we're left with 164.
Take the next digit (3) from the dividend and append it to 164, then repeat: 1643 / 445

Going ahead to step 5:
The number 445 fits into 1643 3 times, leaving a remainder of 308.
Use 3 as the next digit of our solution. 
Result so far: 203.0
Subtract 1335 from 1643 to get 308.
Grab the next digit (1) from the dividend, add it to 308, then carry on: 3081 / 445

Advancing to step 6:
445 goes into 3081 6 times with a remainder of 411.
The next digit of our result is 6. 
Result so far: 2036.0
Deduct 2670 from 3081 and we're left with 411.
Bring next digit (8) of the dividend behind the 411 and repeat the process: 4118 / 445

Going ahead to step 7:
The number 445 fits into 4118 9 times, leaving a remainder of 113.
The next digit of our result is 9. 
Result so far: 20369.0
If we take 4005 away from 4118, we end up with 113.
Fetch the next digit (5) from the dividend, attach it to 113 and continue: 1135 / 445

Advancing to step 8:
1135 divided by 445 is 2 with a remainder of 245.
Write down 2 as next digit of the result. 
Result so far: 203692.0
Deduct 890 from 1135 and we're left with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Going ahead to step 9:
If we divide 2450 by 445, we get 5 and a remainder of 225.
Record the quotient 5 as the next digit in the result. 
Result so far: 203692.5
Subtracting 2225 from 2450 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Going ahead to step 10:
If we divide 2250 by 445, we get 5 and a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 203692.55
If we subtract 2225 from 2250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

In conclusion, the division gives 203692.55 with a balance of 0.025.
