We divide 390554 by 84
We want to figure out the number of times 390554 can be divided by 84.

Advancing to step 1:
The number 84 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 84

Going ahead to step 2:
If we divide 39 by 84, we get 0 and a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Include the next digit (0) from the dividend after 39, then repeat: 390 / 84

Advancing to step 3:
390 divided by 84 is 4 with a remainder of 54.
The next digit of our result is 4. 
Result so far: 4.0
If we take 336 away from 390, we end up with 54.
Grab the next digit (5) from the dividend, add it to 54, then carry on: 545 / 84

Going ahead to step 4:
If we divide 545 by 84, we get 6 and a remainder of 41.
Write down 6 as next digit of the result. 
Result so far: 46.0
Subtract 504 from 545 to get 41.
Include the next digit (5) from the dividend after 41, then repeat: 415 / 84

On to step 5:
415 divided by 84 is 4 with a remainder of 79.
Put 4 as the next digit of the answer. 
Result so far: 464.0
If we subtract 336 from 415, we get 79.
Grab the next digit (4) from the dividend, add it to 79, then carry on: 794 / 84

On to step 6:
84 can be fit into 794 9 times, resulting in a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 4649.0
If we subtract 756 from 794, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 7:
84 can be fit into 380 4 times, resulting in a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 4649.4
If we subtract 336 from 380, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 8:
If we divide 440 by 84, we get 5 and a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 4649.45
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.

Step 9:
84 goes into 200 2 times with a remainder of 32.
The next digit of our result is 2. 
Result so far: 4649.452
Subtract 168 from 200 to 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.

On to step 10:
84 goes into 320 3 times with a remainder of 68.
Record the quotient 3 as the next digit in the result. 
Result so far: 4649.4523
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.

Step 11:
84 goes into 680 8 times with a remainder of 8.
The next digit of our result is 8. 
Result so far: 4649.45238
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.

Moving on to step 12:
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: 4649.45238
Subtract 0 from 80 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.

Step 13:
If we divide 800 by 84, we get 9 and a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 4649.4523809
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.

Step 14:
84 goes into 440 5 times with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 4649.45238095
If we take 420 away from 440, we end up 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 outcome is 4649.45238095, with a leftover of 2e-08.
