We look at the division of 857669 by 70 
We want to figure out the number of times 857669 can be divided by 70.

Going ahead to step 1:
The number 70 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 70

Moving on to step 2:
When dividing 85 by 70, we get 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 1.0
If we take 70 away from 85, we end up with 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 70

Let's proceed to step 3:
70 goes into 157 2 times with a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 140 from 157 and we're left with 17.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 70

Going ahead to step 4:
70 can be fit into 176 2 times, resulting in a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 122.0
If we subtract 140 from 176, we get 36.
Bring next digit (6) of the dividend behind the 36 and repeat the process: 366 / 70

Step 5:
366 divided by 70 is 5 with a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 1225.0
Subtracting 350 from 366 leaves us with 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 70

Moving on to step 6:
70 goes into 169 2 times with a remainder of 29.
Put 2 as the next digit of the answer. 
Result so far: 12252.0
If we take 140 away from 169, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 7:
290 divided by 70 is 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 12252.4
If we subtract 280 from 290, we 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 8:
When dividing 100 by 70, we get 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 12252.41
If we take 70 away from 100, we end up 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.

Step 9:
When dividing 300 by 70, we get 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 12252.414
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 10:
70 can be fit into 200 2 times, resulting in a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 12252.4142
Subtracting 140 from 200 leaves us 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.

On to step 11:
70 can be fit into 600 8 times, resulting in a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 12252.41428
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.

Moving on to step 12:
70 can be fit into 400 5 times, resulting in a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 12252.414285
Subtract 350 from 400 to get 50.
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 13:
500 divided by 70 is 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 12252.4142857
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.

Advancing to step 14:
When dividing 100 by 70, we get 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 12252.41428571
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.

In conclusion, the division gives 12252.41428571 with a balance of 3e-08.
