We're dividing 44635643 by 990 
We want to divide 44635643 by 990.

Moving on to step 1:
When dividing 4 by 990, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 990

Let's proceed to step 2:
990 can be fit into 44 0 times, resulting in a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 44 and we're left with 44.
Append the next digit (6) from the dividend to 44 and continue with: 446 / 990

Going ahead to step 3:
If we divide 446 by 990, we get 0 and a remainder of 446.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 446, we end up with 446.
Take the next digit (3) from the dividend and append it to 446, then repeat: 4463 / 990

Let's proceed to step 4:
When dividing 4463 by 990, we get 4 with a remainder of 503.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 3960 away from 4463, we end up with 503.
Append the next digit (5) from the dividend to 503 and continue with: 5035 / 990

Let's proceed to step 5:
990 can be fit into 5035 5 times, resulting in a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Subtract 4950 from 5035 to get 85.
Take the next digit (6) from the dividend and append it to 85, then repeat: 856 / 990

Let's proceed to step 6:
856 divided by 990 is 0 with a remainder of 856.
Put 0 as the next digit of the answer. 
Result so far: 450.0
Subtract 0 from 856 to get 856.
Grab the next digit (4) from the dividend, add it to 856, then carry on: 8564 / 990

On to step 7:
990 goes into 8564 8 times with a remainder of 644.
Record the quotient 8 as the next digit in the result. 
Result so far: 4508.0
The remainder is 644 after subtracting 7920 from 8564.
Bring next digit (3) of the dividend behind the 644 and repeat the process: 6443 / 990

Step 8:
990 goes into 6443 6 times with a remainder of 503.
Use 6 as the next digit of our solution. 
Result so far: 45086.0
Deduct 5940 from 6443 and we're left with 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

On to step 9:
The number 990 fits into 5030 5 times, leaving a remainder of 80.
Use 5 as the next digit of our solution. 
Result so far: 45086.5
The remainder is 80 after subtracting 4950 from 5030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 10:
990 can be fit into 800 0 times, resulting in a remainder of 800.
The next digit of our result is 0. 
Result so far: 45086.5
Subtract 0 from 800 to get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Advancing to step 11:
The number 990 fits into 8000 8 times, leaving a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 45086.508
The remainder is 80 after subtracting 7920 from 8000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 12:
800 divided by 990 is 0 with a remainder of 800.
The next digit of our result is 0. 
Result so far: 45086.508
If we take 0 away from 800, we end up with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

On to step 13:
The number 990 fits into 8000 8 times, leaving a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 45086.50808
Subtracting 7920 from 8000 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 14:
The number 990 fits into 800 0 times, leaving a remainder of 800.
Record the quotient 0 as the next digit in the result. 
Result so far: 45086.50808
Subtract 0 from 800 to get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Going ahead to step 15:
990 goes into 8000 8 times with a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 45086.5080808
Deduct 7920 from 8000 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 16:
990 goes into 800 0 times with a remainder of 800.
The next digit of our result is 0. 
Result so far: 45086.5080808
The remainder is 800 after subtracting 0 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

In conclusion, the division gives 45086.5080808 with a balance of 8e-07.
