We divide 81042579 by 70
We want to figure out the number of times 81042579 can be divided by 70.

Advancing to step 1:
If we divide 8 by 70, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 70

Step 2:
If we divide 81 by 70, we get 1 and a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 70 away from 81, we end up with 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 70

Step 3:
70 goes into 110 1 times with a remainder of 40.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 40 after subtracting 70 from 110.
Fetch the next digit (4) from the dividend, attach it to 40 and continue: 404 / 70

Going ahead to step 4:
The number 70 fits into 404 5 times, leaving a remainder of 54.
Put 5 as the next digit of the answer. 
Result so far: 115.0
If we subtract 350 from 404, we get 54.
Grab the next digit (2) from the dividend, add it to 54, then carry on: 542 / 70

Going ahead to step 5:
If we divide 542 by 70, we get 7 and a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 1157.0
The remainder is 52 after subtracting 490 from 542.
Bring next digit (5) of the dividend behind the 52 and repeat the process: 525 / 70

Let's proceed to step 6:
70 goes into 525 7 times with a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 11577.0
The remainder is 35 after subtracting 490 from 525.
Take the next digit (7) from the dividend and append it to 35, then repeat: 357 / 70

Moving on to step 7:
357 divided by 70 is 5 with a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 115775.0
Deduct 350 from 357 and we're left with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 70

On to step 8:
The number 70 fits into 79 1 times, leaving a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1157751.0
Deduct 70 from 79 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
When dividing 90 by 70, we get 1 with a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1157751.1
Subtracting 70 from 90 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.

On to step 10:
70 goes into 200 2 times with a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 1157751.12
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.

Let's proceed to step 11:
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: 1157751.128
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.

Advancing to step 12:
If we divide 400 by 70, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 1157751.1285
Deduct 350 from 400 and we're left 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.

Let's proceed 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: 1157751.12857
Deduct 490 from 500 and we're left 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:
70 goes into 100 1 times with a remainder of 30.
The next digit of our result is 1. 
Result so far: 1157751.128571
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 15:
The number 70 fits into 300 4 times, leaving a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 1157751.1285714
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 16:
70 goes into 200 2 times with a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 1157751.12857142
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.

Our division results in 1157751.12857142 with a remaining 6e-08.
