We look at the division of 57521449 by 70 
Our goal is to divide 57521449 by 70.

Step 1:
70 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 70

Going ahead to step 2:
70 goes into 57 0 times with a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 57 after subtracting 0 from 57.
Bring next digit (5) of the dividend behind the 57 and repeat the process: 575 / 70

On to step 3:
When dividing 575 by 70, we get 8 with a remainder of 15.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 560 from 575 and we're left with 15.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 70

Moving on to step 4:
The number 70 fits into 152 2 times, leaving a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 82.0
Subtracting 140 from 152 leaves us with 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 70

Moving on to step 5:
70 goes into 121 1 times with a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 821.0
Subtract 70 from 121 to get 51.
Take the next digit (4) from the dividend and append it to 51, then repeat: 514 / 70

Advancing to step 6:
When dividing 514 by 70, we get 7 with a remainder of 24.
The next digit of our result is 7. 
Result so far: 8217.0
If we subtract 490 from 514, we get 24.
Bring next digit (4) of the dividend behind the 24 and repeat the process: 244 / 70

Moving on to step 7:
70 goes into 244 3 times with a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 82173.0
The remainder is 34 after subtracting 210 from 244.
Append the next digit (9) from the dividend to 34 and continue with: 349 / 70

Step 8:
349 divided by 70 is 4 with a remainder of 69.
Write down 4 as next digit of the result. 
Result so far: 821734.0
If we subtract 280 from 349, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 9:
When dividing 690 by 70, we get 9 with a remainder of 60.
Record the quotient 9 as the next digit in the result. 
Result so far: 821734.9
If we take 630 away from 690, 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.

Going ahead to step 10:
When dividing 600 by 70, we get 8 with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 821734.98
Subtracting 560 from 600 leaves us 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 11:
If we divide 400 by 70, we get 5 and a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 821734.985
The remainder is 50 after subtracting 350 from 400.
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 12:
70 goes into 500 7 times with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 821734.9857
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.

Advancing to step 13:
If we divide 100 by 70, we get 1 and a remainder of 30.
The next digit of our result is 1. 
Result so far: 821734.98571
If we subtract 70 from 100, we 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 14:
If we divide 300 by 70, we get 4 and a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 821734.985714
Subtracting 280 from 300 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.

Let's proceed to step 15:
200 divided by 70 is 2 with a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 821734.9857142
Subtracting 140 from 200 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.

Step 16:
70 goes into 600 8 times with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 821734.98571428
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.

In conclusion, the division gives 821734.98571428 with a balance of 4e-08.
