We divide 870219 by 84
We want to figure out the number of times 870219 can be divided by 84.

Moving on to step 1:
When dividing 8 by 84, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 84

Moving on to step 2:
The number 84 fits into 87 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 3 after subtracting 84 from 87.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 84

Going ahead to step 3:
30 divided by 84 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 30, we end up with 30.
Bring next digit (2) of the dividend behind the 30 and repeat the process: 302 / 84

Moving on to step 4:
If we divide 302 by 84, we get 3 and a remainder of 50.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
If we subtract 252 from 302, we get 50.
Append the next digit (1) from the dividend to 50 and continue with: 501 / 84

Let's proceed to step 5:
84 goes into 501 5 times with a remainder of 81.
Use 5 as the next digit of our solution. 
Result so far: 1035.0
Subtract 420 from 501 to get 81.
Bring next digit (9) of the dividend behind the 81 and repeat the process: 819 / 84

Going ahead to step 6:
When dividing 819 by 84, we get 9 with a remainder of 63.
Write down 9 as next digit of the result. 
Result so far: 10359.0
If we take 756 away from 819, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 7:
If we divide 630 by 84, we get 7 and a remainder of 42.
The next digit of our result is 7. 
Result so far: 10359.7
Subtracting 588 from 630 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 8:
The number 84 fits into 420 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 10359.75
Subtract 420 from 420 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.

Advancing to step 9:
When dividing 0 by 84, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10359.75
If we take 0 away from 0, we end up 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.

Let's proceed to step 10:
The number 84 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10359.75
Subtract 0 from 0 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.

The final result is 10359.75 with a remainder of 0.0.
