We're dividing 129986 by 70 
We want to divide 129986 by 70.

On to step 1:
The number 70 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 70

Step 2:
The number 70 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 70

Step 3:
If we divide 129 by 70, we get 1 and a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 70 from 129, we get 59.
Grab the next digit (9) from the dividend, add it to 59, then carry on: 599 / 70

On to step 4:
70 goes into 599 8 times with a remainder of 39.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtracting 560 from 599 leaves us with 39.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 70

Advancing to step 5:
70 goes into 398 5 times with a remainder of 48.
Use 5 as the next digit of our solution. 
Result so far: 185.0
Subtracting 350 from 398 leaves us with 48.
Fetch the next digit (6) from the dividend, attach it to 48 and continue: 486 / 70

On to step 6:
70 goes into 486 6 times with a remainder of 66.
Write down 6 as next digit of the result. 
Result so far: 1856.0
Subtract 420 from 486 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 7:
70 goes into 660 9 times with a remainder of 30.
Put 9 as the next digit of the answer. 
Result so far: 1856.9
The remainder is 30 after subtracting 630 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
If we divide 300 by 70, we get 4 and a remainder of 20.
The next digit of our result is 4. 
Result so far: 1856.94
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.

Let's proceed to step 9:
70 goes into 200 2 times with a remainder of 60.
The next digit of our result is 2. 
Result so far: 1856.942
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 10:
The number 70 fits into 600 8 times, leaving a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 1856.9428
Deduct 560 from 600 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.

Going ahead to step 11:
When dividing 400 by 70, we get 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 1856.94285
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.

Advancing to step 12:
When dividing 500 by 70, we get 7 with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 1856.942857
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.

Moving on to step 13:
The number 70 fits into 100 1 times, leaving a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1856.9428571
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.

Going ahead to step 14:
70 goes into 300 4 times with a remainder of 20.
The next digit of our result is 4. 
Result so far: 1856.94285714
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.

In conclusion, the division gives 1856.94285714 with a balance of 2e-08.
