We divide 51211272 by 70
Our goal is to divide 51211272 by 70.

Advancing to step 1:
5 divided by 70 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 70

Moving on to step 2:
The number 70 fits into 51 0 times, leaving a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Include the next digit (2) from the dividend after 51, then repeat: 512 / 70

Advancing to step 3:
70 goes into 512 7 times with a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 490 from 512 to get 22.
Append the next digit (1) from the dividend to 22 and continue with: 221 / 70

Advancing to step 4:
70 can be fit into 221 3 times, resulting in a remainder of 11.
The next digit of our result is 3. 
Result so far: 73.0
If we take 210 away from 221, we end up with 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 70

On to step 5:
111 divided by 70 is 1 with a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 731.0
Subtracting 70 from 111 leaves us with 41.
Fetch the next digit (2) from the dividend, attach it to 41 and continue: 412 / 70

Moving on to step 6:
70 can be fit into 412 5 times, resulting in a remainder of 62.
Record the quotient 5 as the next digit in the result. 
Result so far: 7315.0
The remainder is 62 after subtracting 350 from 412.
Fetch the next digit (7) from the dividend, attach it to 62 and continue: 627 / 70

Let's proceed to step 7:
If we divide 627 by 70, we get 8 and a remainder of 67.
Use 8 as the next digit of our solution. 
Result so far: 73158.0
Deduct 560 from 627 and we're left with 67.
Include the next digit (2) from the dividend after 67, then repeat: 672 / 70

Step 8:
If we divide 672 by 70, we get 9 and a remainder of 42.
Put 9 as the next digit of the answer. 
Result so far: 731589.0
If we take 630 away from 672, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 9:
420 divided by 70 is 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 731589.6
If we take 420 away from 420, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
70 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 731589.6
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
70 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 731589.6
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 731589.6 with a remainder of 0.0.
