We look at the division of 1429970 by 860 
Let's see how many times 860 fits into 1429970.

Advancing to step 1:
The number 860 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 860

Let's proceed to step 2:
860 goes into 14 0 times with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 860

Advancing to step 3:
860 goes into 142 0 times with a remainder of 142.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 142 after subtracting 0 from 142.
Append the next digit (9) from the dividend to 142 and continue with: 1429 / 860

Going ahead to step 4:
860 can be fit into 1429 1 times, resulting in a remainder of 569.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 860 away from 1429, we end up with 569.
Fetch the next digit (9) from the dividend, attach it to 569 and continue: 5699 / 860

Moving on to step 5:
5699 divided by 860 is 6 with a remainder of 539.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 5160 from 5699, we get 539.
Grab the next digit (7) from the dividend, add it to 539, then carry on: 5397 / 860

Going ahead to step 6:
860 can be fit into 5397 6 times, resulting in a remainder of 237.
Record the quotient 6 as the next digit in the result. 
Result so far: 166.0
The remainder is 237 after subtracting 5160 from 5397.
Take the next digit (0) from the dividend and append it to 237, then repeat: 2370 / 860

Advancing to step 7:
When dividing 2370 by 860, we get 2 with a remainder of 650.
Write down 2 as next digit of the result. 
Result so far: 1662.0
The remainder is 650 after subtracting 1720 from 2370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

On to step 8:
If we divide 6500 by 860, we get 7 and a remainder of 480.
The next digit of our result is 7. 
Result so far: 1662.7
Subtract 6020 from 6500 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 9:
The number 860 fits into 4800 5 times, leaving a remainder of 500.
Record the quotient 5 as the next digit in the result. 
Result so far: 1662.75
The remainder is 500 after subtracting 4300 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 10:
The number 860 fits into 5000 5 times, leaving a remainder of 700.
The number 5 becomes the next digit in our result. 
Result so far: 1662.755
If we take 4300 away from 5000, we end up with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

The quotient of the division is 1662.755, and the remainder is 0.07.
