We look at the division of 573910 by 70 
We want to figure out the number of times 573910 can be divided by 70.

On to step 1:
70 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 70

Advancing to step 2:
70 goes into 57 0 times with a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Take the next digit (3) from the dividend and append it to 57, then repeat: 573 / 70

Moving on to step 3:
573 divided by 70 is 8 with a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 560 from 573 leaves us with 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 70

Moving on to step 4:
When dividing 139 by 70, we get 1 with a remainder of 69.
The next digit of our result is 1. 
Result so far: 81.0
Subtracting 70 from 139 leaves us with 69.
Include the next digit (1) from the dividend after 69, then repeat: 691 / 70

Step 5:
691 divided by 70 is 9 with a remainder of 61.
The next digit of our result is 9. 
Result so far: 819.0
Subtracting 630 from 691 leaves us with 61.
Bring next digit (0) of the dividend behind the 61 and repeat the process: 610 / 70

Advancing to step 6:
70 can be fit into 610 8 times, resulting in a remainder of 50.
Write down 8 as next digit of the result. 
Result so far: 8198.0
If we take 560 away from 610, 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.

On to step 7:
If we divide 500 by 70, we get 7 and a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 8198.7
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.

Moving on to step 8:
70 can be fit into 100 1 times, resulting in a remainder of 30.
The next digit of our result is 1. 
Result so far: 8198.71
The remainder is 30 after subtracting 70 from 100.
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 9:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 8198.714
Subtract 280 from 300 to 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.

Moving on to step 10:
The number 70 fits into 200 2 times, leaving a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 8198.7142
If we take 140 away from 200, we end up 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 11:
The number 70 fits into 600 8 times, leaving a remainder of 40.
The next digit of our result is 8. 
Result so far: 8198.71428
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 12:
When dividing 400 by 70, we get 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 8198.714285
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.

Moving on to step 13:
If we divide 500 by 70, we get 7 and a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 8198.7142857
If we take 490 away from 500, 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.

Going ahead to step 14:
When dividing 100 by 70, we get 1 with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 8198.71428571
The remainder is 30 after subtracting 70 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 8198.71428571, with a leftover of 3e-08.
