863930 ÷ 70 
We want to figure out the number of times 863930 can be divided by 70.

On 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
The remainder is 8 after subtracting 0 from 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 70

Moving on to step 2:
When dividing 86 by 70, we get 1 with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 70 away from 86, we end up with 16.
Fetch the next digit (3) from the dividend, attach it to 16 and continue: 163 / 70

Moving on to step 3:
70 can be fit into 163 2 times, resulting in a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 140 from 163 to get 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 70

Let's proceed to step 4:
If we divide 239 by 70, we get 3 and a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 123.0
If we subtract 210 from 239, we get 29.
Grab the next digit (3) from the dividend, add it to 29, then carry on: 293 / 70

Moving on to step 5:
If we divide 293 by 70, we get 4 and a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 1234.0
Deduct 280 from 293 and we're left with 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 70

Going ahead to step 6:
70 goes into 130 1 times with a remainder of 60.
Use 1 as the next digit of our solution. 
Result so far: 12341.0
Subtract 70 from 130 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.

Advancing to step 7:
600 divided by 70 is 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 12341.8
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.

Going ahead to step 8:
If we divide 400 by 70, we get 5 and a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 12341.85
Deduct 350 from 400 and we're left 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.

Moving on to step 9:
70 goes into 500 7 times with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 12341.857
Subtract 490 from 500 to 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 10:
When dividing 100 by 70, we get 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 12341.8571
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.

Advancing to step 11:
The number 70 fits into 300 4 times, leaving a remainder of 20.
The next digit of our result is 4. 
Result so far: 12341.85714
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.

Going ahead to step 12:
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: 12341.857142
If we take 140 away from 200, we end up 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 13:
70 can be fit into 600 8 times, resulting in a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 12341.8571428
The remainder is 40 after subtracting 560 from 600.
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 14:
If we divide 400 by 70, we get 5 and a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 12341.85714285
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.

The final outcome is 12341.85714285, with a leftover of 5e-08.
