51670922 ÷ 990 
Let's see how many times 990 fits into 51670922.

Advancing to step 1:
990 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 990

Advancing to step 2:
990 can be fit into 51 0 times, resulting in a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Include the next digit (6) from the dividend after 51, then repeat: 516 / 990

On to step 3:
990 can be fit into 516 0 times, resulting in a remainder of 516.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 516, we get 516.
Fetch the next digit (7) from the dividend, attach it to 516 and continue: 5167 / 990

On to step 4:
The number 990 fits into 5167 5 times, leaving a remainder of 217.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 4950 from 5167, we get 217.
Take the next digit (0) from the dividend and append it to 217, then repeat: 2170 / 990

Step 5:
When dividing 2170 by 990, we get 2 with a remainder of 190.
Put 2 as the next digit of the answer. 
Result so far: 52.0
If we take 1980 away from 2170, we end up with 190.
Bring next digit (9) of the dividend behind the 190 and repeat the process: 1909 / 990

Step 6:
1909 divided by 990 is 1 with a remainder of 919.
The number 1 becomes the next digit in our result. 
Result so far: 521.0
If we take 990 away from 1909, we end up with 919.
Bring next digit (2) of the dividend behind the 919 and repeat the process: 9192 / 990

Let's proceed to step 7:
When dividing 9192 by 990, we get 9 with a remainder of 282.
Write down 9 as next digit of the result. 
Result so far: 5219.0
If we subtract 8910 from 9192, we get 282.
Fetch the next digit (2) from the dividend, attach it to 282 and continue: 2822 / 990

Going ahead to step 8:
990 can be fit into 2822 2 times, resulting in a remainder of 842.
Use 2 as the next digit of our solution. 
Result so far: 52192.0
If we subtract 1980 from 2822, we get 842.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8420, and continue the process.

Let's proceed to step 9:
The number 990 fits into 8420 8 times, leaving a remainder of 500.
Record the quotient 8 as the next digit in the result. 
Result so far: 52192.8
If we take 7920 away from 8420, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 10:
When dividing 5000 by 990, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 52192.85
If we subtract 4950 from 5000, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
If we divide 500 by 990, we get 0 and a remainder of 500.
Record the quotient 0 as the next digit in the result. 
Result so far: 52192.85
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 12:
990 can be fit into 5000 5 times, resulting in a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 52192.8505
Subtracting 4950 from 5000 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
990 can be fit into 500 0 times, resulting in a remainder of 500.
Put 0 as the next digit of the answer. 
Result so far: 52192.8505
Subtract 0 from 500 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 14:
5000 divided by 990 is 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 52192.850505
If we take 4950 away from 5000, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 15:
500 divided by 990 is 0 with a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 52192.850505
Subtract 0 from 500 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 16:
990 can be fit into 5000 5 times, resulting in a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 52192.85050505
The remainder is 50 after subtracting 4950 from 5000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 52192.85050505, and the remainder is 5e-08.
