We're dividing 643070 by 84 
We want to figure out the number of times 643070 can be divided by 84.

Let's proceed to step 1:
If we divide 6 by 84, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 84

Advancing to step 2:
84 can be fit into 64 0 times, resulting in a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Fetch the next digit (3) from the dividend, attach it to 64 and continue: 643 / 84

On to step 3:
84 can be fit into 643 7 times, resulting in a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 588 from 643 and we're left with 55.
Append the next digit (0) from the dividend to 55 and continue with: 550 / 84

Advancing to step 4:
550 divided by 84 is 6 with a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 76.0
If we take 504 away from 550, we end up with 46.
Bring next digit (7) of the dividend behind the 46 and repeat the process: 467 / 84

Going ahead to step 5:
84 can be fit into 467 5 times, resulting in a remainder of 47.
Write down 5 as next digit of the result. 
Result so far: 765.0
Subtracting 420 from 467 leaves us with 47.
Fetch the next digit (0) from the dividend, attach it to 47 and continue: 470 / 84

Let's proceed to step 6:
When dividing 470 by 84, we get 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 7655.0
If we subtract 420 from 470, we 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.

Going ahead to step 7:
84 can be fit into 500 5 times, resulting in a remainder of 80.
Use 5 as the next digit of our solution. 
Result so far: 7655.5
Subtract 420 from 500 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 8:
84 goes into 800 9 times with a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 7655.59
Subtracting 756 from 800 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 9:
The number 84 fits into 440 5 times, leaving a remainder of 20.
The next digit of our result is 5. 
Result so far: 7655.595
The remainder is 20 after subtracting 420 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
84 goes into 200 2 times with a remainder of 32.
The next digit of our result is 2. 
Result so far: 7655.5952
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 11:
84 can be fit into 320 3 times, resulting in a remainder of 68.
Record the quotient 3 as the next digit in the result. 
Result so far: 7655.59523
If we take 252 away from 320, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 12:
When dividing 680 by 84, we get 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 7655.595238
Deduct 672 from 680 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 13:
80 divided by 84 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 7655.595238
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 14:
When dividing 800 by 84, we get 9 with a remainder of 44.
The next digit of our result is 9. 
Result so far: 7655.59523809
If we take 756 away from 800, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 7655.59523809 with a remainder of 4.4e-08.
