864801 ÷ 70 
Our goal is to divide 864801 by 70.

Going ahead to step 1:
If we divide 8 by 70, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 70

Advancing to step 2:
The number 70 fits into 86 1 times, leaving a remainder of 16.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 70 from 86, we get 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 70

Moving on to step 3:
When dividing 164 by 70, we get 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 140 from 164 and we're left with 24.
Grab the next digit (8) from the dividend, add it to 24, then carry on: 248 / 70

Step 4:
When dividing 248 by 70, we get 3 with a remainder of 38.
Record the quotient 3 as the next digit in the result. 
Result so far: 123.0
Subtracting 210 from 248 leaves us with 38.
Grab the next digit (0) from the dividend, add it to 38, then carry on: 380 / 70

Going ahead to step 5:
The number 70 fits into 380 5 times, leaving a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 1235.0
If we take 350 away from 380, we end up with 30.
Fetch the next digit (1) from the dividend, attach it to 30 and continue: 301 / 70

Advancing to step 6:
301 divided by 70 is 4 with a remainder of 21.
The next digit of our result is 4. 
Result so far: 12354.0
Deduct 280 from 301 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
The number 70 fits into 210 3 times, leaving a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 12354.3
Subtract 210 from 210 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
70 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12354.3
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
70 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12354.3
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 12354.3, with a leftover of 0.0.
