We divide 86443 by 70
Let's see how many times 70 fits into 86443.

On to step 1:
The number 70 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 70

Let's proceed to step 2:
When dividing 86 by 70, we get 1 with a remainder of 16.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 70 from 86 to get 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 70

Let's proceed to step 3:
The number 70 fits into 164 2 times, leaving a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 140 from 164 and we're left with 24.
Include the next digit (4) from the dividend after 24, then repeat: 244 / 70

Let's proceed to step 4:
70 goes into 244 3 times with a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 123.0
Deduct 210 from 244 and we're left with 34.
Append the next digit (3) from the dividend to 34 and continue with: 343 / 70

Advancing to step 5:
70 can be fit into 343 4 times, resulting in a remainder of 63.
Use 4 as the next digit of our solution. 
Result so far: 1234.0
Subtract 280 from 343 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 6:
630 divided by 70 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 1234.9
If we subtract 630 from 630, 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.

Advancing to step 7:
The number 70 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1234.9
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
The number 70 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1234.9
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.

The final result is 1234.9 with a remainder of 0.0.
