We're dividing 70430 by 84 
We want to divide 70430 by 84.

Going ahead to step 1:
84 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 84

Advancing to step 2:
When dividing 70 by 84, we get 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Append the next digit (4) from the dividend to 70 and continue with: 704 / 84

Advancing to step 3:
If we divide 704 by 84, we get 8 and a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 672 from 704 and we're left with 32.
Include the next digit (3) from the dividend after 32, then repeat: 323 / 84

Going ahead to step 4:
If we divide 323 by 84, we get 3 and a remainder of 71.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
Subtract 252 from 323 to get 71.
Append the next digit (0) from the dividend to 71 and continue with: 710 / 84

Advancing to step 5:
84 can be fit into 710 8 times, resulting in a remainder of 38.
The next digit of our result is 8. 
Result so far: 838.0
Deduct 672 from 710 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 6:
If we divide 380 by 84, we get 4 and a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 838.4
Deduct 336 from 380 and we're left 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.

Going ahead to step 7:
84 can be fit into 440 5 times, resulting in a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 838.45
Deduct 420 from 440 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
200 divided by 84 is 2 with a remainder of 32.
The next digit of our result is 2. 
Result so far: 838.452
Deduct 168 from 200 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 9:
If we divide 320 by 84, we get 3 and a remainder of 68.
Record the quotient 3 as the next digit in the result. 
Result so far: 838.4523
Subtract 252 from 320 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 10:
If we divide 680 by 84, we get 8 and a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 838.45238
If we take 672 away from 680, we end up 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.

Going ahead to step 11:
If we divide 80 by 84, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 838.45238
If we take 0 away from 80, we end up with 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 12:
If we divide 800 by 84, we get 9 and a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 838.4523809
The remainder is 44 after subtracting 756 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 13:
The number 84 fits into 440 5 times, leaving a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 838.45238095
Deduct 420 from 440 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 838.45238095 with a remainder of 2e-08.
