351819 divided by 84 
We want to divide 351819 by 84.

Let's proceed to step 1:
84 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 84

Moving on to step 2:
If we divide 35 by 84, we get 0 and a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Fetch the next digit (1) from the dividend, attach it to 35 and continue: 351 / 84

Moving on to step 3:
351 divided by 84 is 4 with a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 336 from 351, we get 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 84

Going ahead to step 4:
84 can be fit into 158 1 times, resulting in a remainder of 74.
Write down 1 as next digit of the result. 
Result so far: 41.0
Subtract 84 from 158 to get 74.
Take the next digit (1) from the dividend and append it to 74, then repeat: 741 / 84

Advancing to step 5:
If we divide 741 by 84, we get 8 and a remainder of 69.
The next digit of our result is 8. 
Result so far: 418.0
Subtract 672 from 741 to get 69.
Append the next digit (9) from the dividend to 69 and continue with: 699 / 84

On to step 6:
699 divided by 84 is 8 with a remainder of 27.
Use 8 as the next digit of our solution. 
Result so far: 4188.0
If we take 672 away from 699, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 7:
If we divide 270 by 84, we get 3 and a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 4188.3
Subtracting 252 from 270 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
The number 84 fits into 180 2 times, leaving a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 4188.32
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
84 goes into 120 1 times with a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 4188.321
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 10:
360 divided by 84 is 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 4188.3214
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 11:
If we divide 240 by 84, we get 2 and a remainder of 72.
The next digit of our result is 2. 
Result so far: 4188.32142
Subtract 168 from 240 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 12:
84 goes into 720 8 times with a remainder of 48.
The next digit of our result is 8. 
Result so far: 4188.321428
Subtract 672 from 720 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 13:
When dividing 480 by 84, we get 5 with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 4188.3214285
Subtracting 420 from 480 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 14:
84 goes into 600 7 times with a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 4188.32142857
Subtract 588 from 600 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 4188.32142857, with a leftover of 1.2e-08.
