We're dividing 641022 by 51 
We're looking to find how many times 51 goes into 641022.

Advancing to step 1:
51 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 51

On to step 2:
51 goes into 64 1 times with a remainder of 13.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 51 from 64, we get 13.
Fetch the next digit (1) from the dividend, attach it to 13 and continue: 131 / 51

Let's proceed to step 3:
When dividing 131 by 51, we get 2 with a remainder of 29.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 29 after subtracting 102 from 131.
Append the next digit (0) from the dividend to 29 and continue with: 290 / 51

Step 4:
290 divided by 51 is 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 125.0
The remainder is 35 after subtracting 255 from 290.
Include the next digit (2) from the dividend after 35, then repeat: 352 / 51

Let's proceed to step 5:
The number 51 fits into 352 6 times, leaving a remainder of 46.
The next digit of our result is 6. 
Result so far: 1256.0
If we subtract 306 from 352, we get 46.
Take the next digit (2) from the dividend and append it to 46, then repeat: 462 / 51

On to step 6:
If we divide 462 by 51, we get 9 and a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 12569.0
The remainder is 3 after subtracting 459 from 462.
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 7:
30 divided by 51 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 12569.0
Subtracting 0 from 30 leaves us 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.

Advancing to step 8:
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: 12569.05
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.

Let's proceed to step 9:
51 goes into 450 8 times with a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 12569.058
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.

Step 10:
The number 51 fits into 420 8 times, leaving a remainder of 12.
The next digit of our result is 8. 
Result so far: 12569.0588
Subtract 408 from 420 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 12569.0588 with a remaining 0.00012.
