Let's divide 383521 by 84
We want to divide 383521 by 84.

Moving on to step 1:
84 can be fit into 3 0 times, resulting in 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.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 84

Advancing to step 2:
When dividing 38 by 84, we get 0 with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Take the next digit (3) from the dividend and append it to 38, then repeat: 383 / 84

Step 3:
If we divide 383 by 84, we get 4 and a remainder of 47.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 336 from 383 leaves us with 47.
Include the next digit (5) from the dividend after 47, then repeat: 475 / 84

Advancing to step 4:
84 can be fit into 475 5 times, resulting in a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 45.0
If we take 420 away from 475, we end up with 55.
Grab the next digit (2) from the dividend, add it to 55, then carry on: 552 / 84

On to step 5:
When dividing 552 by 84, we get 6 with a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 456.0
Subtract 504 from 552 to get 48.
Include the next digit (1) from the dividend after 48, then repeat: 481 / 84

Advancing to step 6:
If we divide 481 by 84, we get 5 and a remainder of 61.
The number 5 becomes the next digit in our result. 
Result so far: 4565.0
If we take 420 away from 481, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 7:
84 goes into 610 7 times with a remainder of 22.
The next digit of our result is 7. 
Result so far: 4565.7
Subtracting 588 from 610 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
220 divided by 84 is 2 with a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 4565.72
The remainder is 52 after subtracting 168 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 9:
520 divided by 84 is 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 4565.726
The remainder is 16 after subtracting 504 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
When dividing 160 by 84, we get 1 with a remainder of 76.
Record the quotient 1 as the next digit in the result. 
Result so far: 4565.7261
Subtracting 84 from 160 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 11:
760 divided by 84 is 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 4565.72619
Subtract 756 from 760 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
The number 84 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 4565.72619
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
400 divided by 84 is 4 with a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 4565.7261904
Subtracting 336 from 400 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 14:
84 goes into 640 7 times with a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 4565.72619047
The remainder is 52 after subtracting 588 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final result is 4565.72619047 with a remainder of 5.2e-08.
