Let's divide 991629 by 51
Let's see how many times 51 fits into 991629.

Step 1:
When dividing 9 by 51, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 51

Going ahead to step 2:
If we divide 99 by 51, we get 1 and a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 51 from 99 leaves us with 48.
Append the next digit (1) from the dividend to 48 and continue with: 481 / 51

On to step 3:
51 goes into 481 9 times with a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 19.0
The remainder is 22 after subtracting 459 from 481.
Include the next digit (6) from the dividend after 22, then repeat: 226 / 51

Step 4:
51 can be fit into 226 4 times, resulting in a remainder of 22.
The next digit of our result is 4. 
Result so far: 194.0
Subtract 204 from 226 to get 22.
Append the next digit (2) from the dividend to 22 and continue with: 222 / 51

Let's proceed to step 5:
222 divided by 51 is 4 with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 1944.0
If we subtract 204 from 222, we get 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 51

Going ahead to step 6:
When dividing 189 by 51, we get 3 with a remainder of 36.
Use 3 as the next digit of our solution. 
Result so far: 19443.0
If we subtract 153 from 189, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 7:
When dividing 360 by 51, we get 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 19443.7
Deduct 357 from 360 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 8:
51 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 19443.7
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
51 can be fit into 300 5 times, resulting in a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 19443.705
Deduct 255 from 300 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 10:
If we divide 450 by 51, we get 8 and a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 19443.7058
The remainder is 42 after subtracting 408 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 11:
If we divide 420 by 51, we get 8 and a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 19443.70588
Deduct 408 from 420 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 19443.70588, and the remainder is 1.2e-05.
