50215981 ÷ 990 
We want to divide 50215981 by 990.

On to step 1:
The number 990 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 990

Step 2:
When dividing 50 by 990, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 50, we end up with 50.
Fetch the next digit (2) from the dividend, attach it to 50 and continue: 502 / 990

Going ahead to step 3:
990 goes into 502 0 times with a remainder of 502.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 502 leaves us with 502.
Append the next digit (1) from the dividend to 502 and continue with: 5021 / 990

Step 4:
990 can be fit into 5021 5 times, resulting in a remainder of 71.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 4950 from 5021 and we're left with 71.
Include the next digit (5) from the dividend after 71, then repeat: 715 / 990

Advancing to step 5:
990 goes into 715 0 times with a remainder of 715.
Put 0 as the next digit of the answer. 
Result so far: 50.0
Deduct 0 from 715 and we're left with 715.
Bring next digit (9) of the dividend behind the 715 and repeat the process: 7159 / 990

Let's proceed to step 6:
If we divide 7159 by 990, we get 7 and a remainder of 229.
Record the quotient 7 as the next digit in the result. 
Result so far: 507.0
Deduct 6930 from 7159 and we're left with 229.
Grab the next digit (8) from the dividend, add it to 229, then carry on: 2298 / 990

Let's proceed to step 7:
2298 divided by 990 is 2 with a remainder of 318.
Write down 2 as next digit of the result. 
Result so far: 5072.0
If we take 1980 away from 2298, we end up with 318.
Append the next digit (1) from the dividend to 318 and continue with: 3181 / 990

Let's proceed to step 8:
990 goes into 3181 3 times with a remainder of 211.
The number 3 becomes the next digit in our result. 
Result so far: 50723.0
The remainder is 211 after subtracting 2970 from 3181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

On to step 9:
When dividing 2110 by 990, we get 2 with a remainder of 130.
Write down 2 as next digit of the result. 
Result so far: 50723.2
Subtract 1980 from 2110 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 10:
1300 divided by 990 is 1 with a remainder of 310.
Write down 1 as next digit of the result. 
Result so far: 50723.21
If we subtract 990 from 1300, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 11:
The number 990 fits into 3100 3 times, leaving a remainder of 130.
Write down 3 as next digit of the result. 
Result so far: 50723.213
Subtracting 2970 from 3100 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 12:
When dividing 1300 by 990, we get 1 with a remainder of 310.
Write down 1 as next digit of the result. 
Result so far: 50723.2131
If we subtract 990 from 1300, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 13:
990 goes into 3100 3 times with a remainder of 130.
Write down 3 as next digit of the result. 
Result so far: 50723.21313
Deduct 2970 from 3100 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 14:
The number 990 fits into 1300 1 times, leaving a remainder of 310.
Write down 1 as next digit of the result. 
Result so far: 50723.213131
Subtracting 990 from 1300 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 15:
The number 990 fits into 3100 3 times, leaving a remainder of 130.
Use 3 as the next digit of our solution. 
Result so far: 50723.2131313
Subtract 2970 from 3100 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 16:
990 can be fit into 1300 1 times, resulting in a remainder of 310.
Use 1 as the next digit of our solution. 
Result so far: 50723.21313131
The remainder is 310 after subtracting 990 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

In conclusion, the division gives 50723.21313131 with a balance of 3.1e-07.
