129975 divided by 70 
Let's see how many times 70 fits into 129975.

On to step 1:
If we divide 1 by 70, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 70

Going ahead to step 2:
12 divided by 70 is 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 70

Advancing to step 3:
70 goes into 129 1 times with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 59 after subtracting 70 from 129.
Include the next digit (9) from the dividend after 59, then repeat: 599 / 70

Let's proceed to step 4:
The number 70 fits into 599 8 times, leaving a remainder of 39.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtract 560 from 599 to get 39.
Fetch the next digit (7) from the dividend, attach it to 39 and continue: 397 / 70

Let's proceed to step 5:
397 divided by 70 is 5 with a remainder of 47.
Record the quotient 5 as the next digit in the result. 
Result so far: 185.0
The remainder is 47 after subtracting 350 from 397.
Grab the next digit (5) from the dividend, add it to 47, then carry on: 475 / 70

On to step 6:
70 can be fit into 475 6 times, resulting in a remainder of 55.
Put 6 as the next digit of the answer. 
Result so far: 1856.0
The remainder is 55 after subtracting 420 from 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 7:
70 goes into 550 7 times with a remainder of 60.
Use 7 as the next digit of our solution. 
Result so far: 1856.7
The remainder is 60 after subtracting 490 from 550.
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 8:
600 divided by 70 is 8 with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 1856.78
If we subtract 560 from 600, we get 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 9:
400 divided by 70 is 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 1856.785
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.

Advancing to step 10:
When dividing 500 by 70, we get 7 with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 1856.7857
The remainder is 10 after subtracting 490 from 500.
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 11:
70 goes into 100 1 times with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1856.78571
Deduct 70 from 100 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
70 goes into 300 4 times with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 1856.785714
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.

On to step 13:
200 divided by 70 is 2 with a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 1856.7857142
If we subtract 140 from 200, we 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.

Step 14:
70 goes into 600 8 times with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 1856.78571428
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.

In conclusion, the division gives 1856.78571428 with a balance of 4e-08.
