Let's divide 609721 by 70
We're looking to find how many times 70 goes into 609721.

On to step 1:
6 divided by 70 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 70

Advancing to step 2:
60 divided by 70 is 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 60, we end up with 60.
Take the next digit (9) from the dividend and append it to 60, then repeat: 609 / 70

On to step 3:
70 can be fit into 609 8 times, resulting in a remainder of 49.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 49 after subtracting 560 from 609.
Append the next digit (7) from the dividend to 49 and continue with: 497 / 70

Moving on to step 4:
70 can be fit into 497 7 times, resulting in a remainder of 7.
The next digit of our result is 7. 
Result so far: 87.0
Subtracting 490 from 497 leaves us with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 70

Going ahead to step 5:
When dividing 72 by 70, we get 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 871.0
Subtract 70 from 72 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 70

Step 6:
The number 70 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 8710.0
Subtract 0 from 21 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
When dividing 210 by 70, we get 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 8710.3
Subtracting 210 from 210 leaves us 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.

Advancing to step 8:
The number 70 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 8710.3
Subtract 0 from 0 to get 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 9:
70 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 8710.3
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 8710.3 with a remaining 0.0.
