852139 ÷ 70 
We're looking to find how many times 70 goes into 852139.

Advancing to step 1:
70 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 70

On to step 2:
If we divide 85 by 70, we get 1 and a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 15 after subtracting 70 from 85.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 70

Let's proceed to step 3:
70 goes into 152 2 times with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 12 after subtracting 140 from 152.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 70

Step 4:
If we divide 121 by 70, we get 1 and a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 121.0
If we take 70 away from 121, we end up with 51.
Append the next digit (3) from the dividend to 51 and continue with: 513 / 70

Advancing to step 5:
70 can be fit into 513 7 times, resulting in a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 1217.0
Subtract 490 from 513 to get 23.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 70

Going ahead to step 6:
239 divided by 70 is 3 with a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 12173.0
Deduct 210 from 239 and we're left 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.

Moving on to step 7:
70 goes into 290 4 times with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 12173.4
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.

Advancing to step 8:
70 goes into 100 1 times with a remainder of 30.
The next digit of our result is 1. 
Result so far: 12173.41
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.

Going ahead to step 9:
If we divide 300 by 70, we get 4 and a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 12173.414
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.

Step 10:
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: 12173.4142
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.

Let's proceed to step 11:
When dividing 600 by 70, we get 8 with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 12173.41428
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.

Going ahead to step 12:
The number 70 fits into 400 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 12173.414285
If we subtract 350 from 400, we 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.

Advancing to step 13:
70 goes into 500 7 times with a remainder of 10.
The next digit of our result is 7. 
Result so far: 12173.4142857
Subtracting 490 from 500 leaves us 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 14:
If we divide 100 by 70, we get 1 and a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 12173.41428571
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.

The quotient of the division is 12173.41428571, and the remainder is 3e-08.
