Let's divide 84421523 by 990
We want to divide 84421523 by 990.

Let's proceed to step 1:
990 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 990

Going ahead to step 2:
The number 990 fits into 84 0 times, leaving a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Fetch the next digit (4) from the dividend, attach it to 84 and continue: 844 / 990

Going ahead to step 3:
When dividing 844 by 990, we get 0 with a remainder of 844.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 844, we get 844.
Fetch the next digit (2) from the dividend, attach it to 844 and continue: 8442 / 990

Going ahead to step 4:
8442 divided by 990 is 8 with a remainder of 522.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 7920 from 8442 and we're left with 522.
Append the next digit (1) from the dividend to 522 and continue with: 5221 / 990

Let's proceed to step 5:
If we divide 5221 by 990, we get 5 and a remainder of 271.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
The remainder is 271 after subtracting 4950 from 5221.
Take the next digit (5) from the dividend and append it to 271, then repeat: 2715 / 990

Moving on to step 6:
When dividing 2715 by 990, we get 2 with a remainder of 735.
The next digit of our result is 2. 
Result so far: 852.0
Subtracting 1980 from 2715 leaves us with 735.
Bring next digit (2) of the dividend behind the 735 and repeat the process: 7352 / 990

Going ahead to step 7:
When dividing 7352 by 990, we get 7 with a remainder of 422.
Use 7 as the next digit of our solution. 
Result so far: 8527.0
If we subtract 6930 from 7352, we get 422.
Fetch the next digit (3) from the dividend, attach it to 422 and continue: 4223 / 990

Going ahead to step 8:
If we divide 4223 by 990, we get 4 and a remainder of 263.
Record the quotient 4 as the next digit in the result. 
Result so far: 85274.0
Subtracting 3960 from 4223 leaves us with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Advancing to step 9:
2630 divided by 990 is 2 with a remainder of 650.
The next digit of our result is 2. 
Result so far: 85274.2
Subtracting 1980 from 2630 leaves us with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Advancing to step 10:
6500 divided by 990 is 6 with a remainder of 560.
Write down 6 as next digit of the result. 
Result so far: 85274.26
The remainder is 560 after subtracting 5940 from 6500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 11:
If we divide 5600 by 990, we get 5 and a remainder of 650.
The number 5 becomes the next digit in our result. 
Result so far: 85274.265
If we subtract 4950 from 5600, we get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Step 12:
990 can be fit into 6500 6 times, resulting in a remainder of 560.
Put 6 as the next digit of the answer. 
Result so far: 85274.2656
If we subtract 5940 from 6500, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

On to step 13:
When dividing 5600 by 990, we get 5 with a remainder of 650.
Record the quotient 5 as the next digit in the result. 
Result so far: 85274.26565
If we subtract 4950 from 5600, we get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Moving on to step 14:
6500 divided by 990 is 6 with a remainder of 560.
The number 6 becomes the next digit in our result. 
Result so far: 85274.265656
If we take 5940 away from 6500, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 15:
990 goes into 5600 5 times with a remainder of 650.
Put 5 as the next digit of the answer. 
Result so far: 85274.2656565
Subtracting 4950 from 5600 leaves us with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Going ahead to step 16:
6500 divided by 990 is 6 with a remainder of 560.
Put 6 as the next digit of the answer. 
Result so far: 85274.26565656
If we subtract 5940 from 6500, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Our division results in 85274.26565656 with a remaining 5.6e-07.
