839001 divided by 70 
Let's see how many times 70 fits into 839001.

On to step 1:
70 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 70

On to step 2:
The number 70 fits into 83 1 times, leaving a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 70 from 83 leaves us with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 70

Let's proceed to step 3:
139 divided by 70 is 1 with a remainder of 69.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 69 after subtracting 70 from 139.
Take the next digit (0) from the dividend and append it to 69, then repeat: 690 / 70

Let's proceed to step 4:
70 goes into 690 9 times with a remainder of 60.
The next digit of our result is 9. 
Result so far: 119.0
Subtracting 630 from 690 leaves us with 60.
Take the next digit (0) from the dividend and append it to 60, then repeat: 600 / 70

Moving on to step 5:
70 can be fit into 600 8 times, resulting in a remainder of 40.
The next digit of our result is 8. 
Result so far: 1198.0
The remainder is 40 after subtracting 560 from 600.
Take the next digit (1) from the dividend and append it to 40, then repeat: 401 / 70

On to step 6:
When dividing 401 by 70, we get 5 with a remainder of 51.
Put 5 as the next digit of the answer. 
Result so far: 11985.0
Subtracting 350 from 401 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 7:
510 divided by 70 is 7 with a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 11985.7
If we take 490 away from 510, we end up with 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 8:
The number 70 fits into 200 2 times, leaving a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 11985.72
The remainder is 60 after subtracting 140 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
70 goes into 600 8 times with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 11985.728
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.

Advancing to step 10:
70 can be fit into 400 5 times, resulting in a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 11985.7285
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 11:
70 goes into 500 7 times with a remainder of 10.
The next digit of our result is 7. 
Result so far: 11985.72857
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.

Let's proceed to step 12:
70 goes into 100 1 times with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 11985.728571
Subtracting 70 from 100 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.

On to step 13:
The number 70 fits into 300 4 times, leaving a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 11985.7285714
Deduct 280 from 300 and we're left with 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 14:
70 can be fit into 200 2 times, resulting in a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 11985.72857142
Deduct 140 from 200 and we're left 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.

The final outcome is 11985.72857142, with a leftover of 6e-08.
