Let's divide 857139 by 70
We're looking to find how many times 70 goes into 857139.

Advancing to step 1:
If we divide 8 by 70, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 70

Let's proceed to step 2:
85 divided by 70 is 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 70 from 85 to get 15.
Include the next digit (7) from the dividend after 15, then repeat: 157 / 70

Moving on to step 3:
When dividing 157 by 70, we get 2 with a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 140 from 157 and we're left with 17.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 70

Going ahead to step 4:
The number 70 fits into 171 2 times, leaving a remainder of 31.
The number 2 becomes the next digit in our result. 
Result so far: 122.0
Subtracting 140 from 171 leaves us with 31.
Take the next digit (3) from the dividend and append it to 31, then repeat: 313 / 70

On to step 5:
70 goes into 313 4 times with a remainder of 33.
Put 4 as the next digit of the answer. 
Result so far: 1224.0
The remainder is 33 after subtracting 280 from 313.
Grab the next digit (9) from the dividend, add it to 33, then carry on: 339 / 70

On to step 6:
If we divide 339 by 70, we get 4 and a remainder of 59.
The number 4 becomes the next digit in our result. 
Result so far: 12244.0
Deduct 280 from 339 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 7:
When dividing 590 by 70, we get 8 with a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 12244.8
Subtracting 560 from 590 leaves us 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.

Let's proceed to step 8:
300 divided by 70 is 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 12244.84
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.

Advancing to step 9:
The number 70 fits into 200 2 times, leaving a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 12244.842
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.

Step 10:
If we divide 600 by 70, we get 8 and a remainder of 40.
The next digit of our result is 8. 
Result so far: 12244.8428
If we take 560 away from 600, we end up 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.

On to step 11:
400 divided by 70 is 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 12244.84285
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.

Step 12:
When dividing 500 by 70, we get 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 12244.842857
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.

Let's proceed to step 13:
70 can be fit into 100 1 times, resulting in a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 12244.8428571
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.

On to step 14:
70 goes into 300 4 times with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 12244.84285714
The remainder is 20 after subtracting 280 from 300.
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 12244.84285714 with a balance of 2e-08.
