We're dividing 135391 by 70 
We want to divide 135391 by 70.

On to step 1:
If we divide 1 by 70, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 70

Going ahead to step 2:
70 goes into 13 0 times with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 70

Going ahead to step 3:
The number 70 fits into 135 1 times, leaving a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 70 from 135 to get 65.
Grab the next digit (3) from the dividend, add it to 65, then carry on: 653 / 70

Going ahead to step 4:
When dividing 653 by 70, we get 9 with a remainder of 23.
The next digit of our result is 9. 
Result so far: 19.0
Subtracting 630 from 653 leaves us with 23.
Bring next digit (9) of the dividend behind the 23 and repeat the process: 239 / 70

Let's proceed to step 5:
If we divide 239 by 70, we get 3 and a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 193.0
If we take 210 away from 239, we end up with 29.
Append the next digit (1) from the dividend to 29 and continue with: 291 / 70

Going ahead to step 6:
70 can be fit into 291 4 times, resulting in a remainder of 11.
The next digit of our result is 4. 
Result so far: 1934.0
Subtracting 280 from 291 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
The number 70 fits into 110 1 times, leaving a remainder of 40.
The next digit of our result is 1. 
Result so far: 1934.1
Deduct 70 from 110 and we're left 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 8:
If we divide 400 by 70, we get 5 and a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 1934.15
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.

Going ahead to step 9:
When dividing 500 by 70, we get 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 1934.157
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.

On to step 10:
The number 70 fits into 100 1 times, leaving a remainder of 30.
The next digit of our result is 1. 
Result so far: 1934.1571
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.

Moving on to step 11:
If we divide 300 by 70, we get 4 and a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 1934.15714
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.

Let's proceed to step 12:
The number 70 fits into 200 2 times, leaving a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 1934.157142
Subtract 140 from 200 to get 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 13:
70 goes into 600 8 times with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 1934.1571428
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.

Moving on to step 14:
The number 70 fits into 400 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 1934.15714285
If we take 350 away from 400, 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.

The final result is 1934.15714285 with a remainder of 5e-08.
