722428 ÷ 51 
Our goal is to divide 722428 by 51.

Moving on to step 1:
If we divide 7 by 51, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 51

Let's proceed to step 2:
If we divide 72 by 51, we get 1 and a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 51 away from 72, we end up with 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 51

On to step 3:
51 can be fit into 212 4 times, resulting in a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we subtract 204 from 212, we get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 51

Moving on to step 4:
84 divided by 51 is 1 with a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 141.0
If we take 51 away from 84, we end up with 33.
Fetch the next digit (2) from the dividend, attach it to 33 and continue: 332 / 51

On to step 5:
51 can be fit into 332 6 times, resulting in a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 1416.0
If we take 306 away from 332, we end up with 26.
Grab the next digit (8) from the dividend, add it to 26, then carry on: 268 / 51

Moving on to step 6:
If we divide 268 by 51, we get 5 and a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 14165.0
The remainder is 13 after subtracting 255 from 268.
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:
130 divided by 51 is 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 14165.2
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:
If we divide 280 by 51, we get 5 and a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 14165.25
The remainder is 25 after subtracting 255 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 9:
51 can be fit into 250 4 times, resulting in a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 14165.254
Deduct 204 from 250 and we're left 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.

On to step 10:
If we divide 460 by 51, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 14165.2549
If we subtract 459 from 460, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 11:
10 divided by 51 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 14165.2549
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:
If we divide 100 by 51, we get 1 and a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 14165.254901
Deduct 51 from 100 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 13:
51 can be fit into 490 9 times, resulting in a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 14165.2549019
Subtracting 459 from 490 leaves us 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.

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: 14165.25490196
The remainder is 4 after subtracting 306 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 14165.25490196 with a remainder of 4e-09.
