Let's divide 642256 by 51
We're looking to find how many times 51 goes into 642256.

Going ahead to step 1:
51 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
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

Step 2:
When dividing 64 by 51, we get 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 51 from 64, we get 13.
Fetch the next digit (2) from the dividend, attach it to 13 and continue: 132 / 51

Let's proceed to step 3:
If we divide 132 by 51, we get 2 and a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 102 from 132, we get 30.
Take the next digit (2) from the dividend and append it to 30, then repeat: 302 / 51

Going ahead to step 4:
51 can be fit into 302 5 times, resulting in a remainder of 47.
Record the quotient 5 as the next digit in the result. 
Result so far: 125.0
Deduct 255 from 302 and we're left with 47.
Append the next digit (5) from the dividend to 47 and continue with: 475 / 51

Advancing to step 5:
51 goes into 475 9 times with a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 1259.0
If we take 459 away from 475, we end up with 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 51

On to step 6:
51 goes into 166 3 times with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 12593.0
If we take 153 away from 166, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
51 can be fit into 130 2 times, resulting in a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 12593.2
Deduct 102 from 130 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 8:
280 divided by 51 is 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 12593.25
If we take 255 away from 280, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
250 divided by 51 is 4 with a remainder of 46.
The next digit of our result is 4. 
Result so far: 12593.254
Subtracting 204 from 250 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 10:
51 goes into 460 9 times with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 12593.2549
If we take 459 away from 460, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 11:
When dividing 10 by 51, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 12593.2549
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
The number 51 fits into 100 1 times, leaving a remainder of 49.
The next digit of our result is 1. 
Result so far: 12593.254901
The remainder is 49 after subtracting 51 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 13:
If we divide 490 by 51, we get 9 and a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 12593.2549019
Deduct 459 from 490 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 14:
When dividing 310 by 51, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 12593.25490196
If we subtract 306 from 310, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 12593.25490196, and the remainder is 4e-09.
