We're dividing 641057 by 51 
We want to figure out the number of times 641057 can be divided by 51.

Step 1:
51 can be fit into 6 0 times, resulting in 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.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 51

Step 2:
The number 51 fits into 64 1 times, leaving a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 51 from 64 to get 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 51

Advancing to step 3:
The number 51 fits into 131 2 times, leaving a remainder of 29.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 29 after subtracting 102 from 131.
Fetch the next digit (0) from the dividend, attach it to 29 and continue: 290 / 51

Advancing to step 4:
290 divided by 51 is 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 125.0
The remainder is 35 after subtracting 255 from 290.
Fetch the next digit (5) from the dividend, attach it to 35 and continue: 355 / 51

Moving on to step 5:
If we divide 355 by 51, we get 6 and a remainder of 49.
Use 6 as the next digit of our solution. 
Result so far: 1256.0
Subtract 306 from 355 to get 49.
Append the next digit (7) from the dividend to 49 and continue with: 497 / 51

On to step 6:
When dividing 497 by 51, we get 9 with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 12569.0
Deduct 459 from 497 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 7:
The number 51 fits into 380 7 times, leaving a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 12569.7
Subtract 357 from 380 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 8:
51 goes into 230 4 times with a remainder of 26.
The next digit of our result is 4. 
Result so far: 12569.74
Subtract 204 from 230 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 9:
51 can be fit into 260 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 12569.745
Subtracting 255 from 260 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 10:
When dividing 50 by 51, we get 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 12569.745
Subtracting 0 from 50 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 11:
The number 51 fits into 500 9 times, leaving a remainder of 41.
The next digit of our result is 9. 
Result so far: 12569.74509
If we subtract 459 from 500, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 12:
The number 51 fits into 410 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 12569.745098
If we take 408 away from 410, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 13:
20 divided by 51 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 12569.745098
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
51 goes into 200 3 times with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 12569.74509803
Subtract 153 from 200 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

After the division, we end up with 12569.74509803 and a remainder of 4.7e-08.
