We look at the division of 422720 by 70 
We want to figure out the number of times 422720 can be divided by 70.

Step 1:
If we divide 4 by 70, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 70

On to step 2:
42 divided by 70 is 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Include the next digit (2) from the dividend after 42, then repeat: 422 / 70

On to step 3:
When dividing 422 by 70, we get 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 420 from 422 and we're left with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 70

Advancing to step 4:
70 can be fit into 27 0 times, resulting in a remainder of 27.
The next digit of our result is 0. 
Result so far: 60.0
If we subtract 0 from 27, we get 27.
Append the next digit (2) from the dividend to 27 and continue with: 272 / 70

Let's proceed to step 5:
The number 70 fits into 272 3 times, leaving a remainder of 62.
The next digit of our result is 3. 
Result so far: 603.0
The remainder is 62 after subtracting 210 from 272.
Take the next digit (0) from the dividend and append it to 62, then repeat: 620 / 70

Going ahead to step 6:
620 divided by 70 is 8 with a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 6038.0
Subtracting 560 from 620 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 7:
70 can be fit into 600 8 times, resulting in a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 6038.8
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.

Let's proceed to step 8:
70 goes into 400 5 times with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 6038.85
If we subtract 350 from 400, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 9:
70 can be fit into 500 7 times, resulting in a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 6038.857
If we subtract 490 from 500, we 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.

Advancing to step 10:
70 can be fit into 100 1 times, resulting in a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 6038.8571
Subtracting 70 from 100 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
300 divided by 70 is 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 6038.85714
If we take 280 away from 300, we end up 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 12:
70 goes into 200 2 times with a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 6038.857142
Deduct 140 from 200 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 13:
70 can be fit into 600 8 times, resulting in a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 6038.8571428
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
70 goes into 400 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 6038.85714285
Subtract 350 from 400 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 6038.85714285 with a balance of 5e-08.
