We look at the division of 397364 by 84 
We want to figure out the number of times 397364 can be divided by 84.

Advancing to step 1:
The number 84 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 84

Moving on to step 2:
84 goes into 39 0 times with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Fetch the next digit (7) from the dividend, attach it to 39 and continue: 397 / 84

Going ahead to step 3:
If we divide 397 by 84, we get 4 and a remainder of 61.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 336 away from 397, we end up with 61.
Take the next digit (3) from the dividend and append it to 61, then repeat: 613 / 84

Moving on to step 4:
613 divided by 84 is 7 with a remainder of 25.
The next digit of our result is 7. 
Result so far: 47.0
Subtracting 588 from 613 leaves us with 25.
Grab the next digit (6) from the dividend, add it to 25, then carry on: 256 / 84

Step 5:
84 goes into 256 3 times with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 473.0
If we subtract 252 from 256, we get 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 84

On to step 6:
If we divide 44 by 84, we get 0 and a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 4730.0
Deduct 0 from 44 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.

Let's proceed to step 7:
When dividing 440 by 84, we get 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 4730.5
If we subtract 420 from 440, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
When dividing 200 by 84, we get 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 4730.52
Subtracting 168 from 200 leaves us 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.

On to step 9:
84 can be fit into 320 3 times, resulting in a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 4730.523
Deduct 252 from 320 and we're left 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 10:
84 goes into 680 8 times with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 4730.5238
If we subtract 672 from 680, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
If we divide 80 by 84, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 4730.5238
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.

Let's proceed to step 12:
84 goes into 800 9 times with a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 4730.523809
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.

Advancing to step 13:
If we divide 440 by 84, we get 5 and a remainder of 20.
The next digit of our result is 5. 
Result so far: 4730.5238095
Subtracting 420 from 440 leaves us 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 14:
If we divide 200 by 84, we get 2 and a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 4730.52380952
Subtracting 168 from 200 leaves us 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.

The final outcome is 4730.52380952, with a leftover of 3.2e-08.
