We look at the division of 521334 by 70 
We want to divide 521334 by 70.

On to step 1:
5 divided by 70 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 70

On to step 2:
If we divide 52 by 70, we get 0 and a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Grab the next digit (1) from the dividend, add it to 52, then carry on: 521 / 70

Let's proceed to step 3:
70 can be fit into 521 7 times, resulting in a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 490 from 521 leaves us with 31.
Append the next digit (3) from the dividend to 31 and continue with: 313 / 70

Step 4:
313 divided by 70 is 4 with a remainder of 33.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
The remainder is 33 after subtracting 280 from 313.
Take the next digit (3) from the dividend and append it to 33, then repeat: 333 / 70

Moving on to step 5:
70 goes into 333 4 times with a remainder of 53.
Put 4 as the next digit of the answer. 
Result so far: 744.0
The remainder is 53 after subtracting 280 from 333.
Append the next digit (4) from the dividend to 53 and continue with: 534 / 70

Going ahead to step 6:
534 divided by 70 is 7 with a remainder of 44.
Put 7 as the next digit of the answer. 
Result so far: 7447.0
If we subtract 490 from 534, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 7:
If we divide 440 by 70, we get 6 and a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 7447.6
Subtracting 420 from 440 leaves us 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.

Going ahead to step 8:
When dividing 200 by 70, we get 2 with a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 7447.62
Subtract 140 from 200 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
The number 70 fits into 600 8 times, leaving a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 7447.628
If we take 560 away from 600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
400 divided by 70 is 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 7447.6285
If we take 350 away from 400, we end up 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.

Advancing to step 11:
70 goes into 500 7 times with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 7447.62857
Subtract 490 from 500 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
The number 70 fits into 100 1 times, leaving a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 7447.628571
Subtract 70 from 100 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
When dividing 300 by 70, we get 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 7447.6285714
If we subtract 280 from 300, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 14:
70 can be fit into 200 2 times, resulting in a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 7447.62857142
The remainder is 60 after subtracting 140 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 7447.62857142 and a remainder of 6e-08.
