We're dividing 391570 by 83 
Our goal is to divide 391570 by 83.

Moving on to step 1:
The number 83 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 83

On to step 2:
83 can be fit into 39 0 times, resulting in a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Grab the next digit (1) from the dividend, add it to 39, then carry on: 391 / 83

Moving on to step 3:
The number 83 fits into 391 4 times, leaving a remainder of 59.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 332 from 391 leaves us with 59.
Bring next digit (5) of the dividend behind the 59 and repeat the process: 595 / 83

Advancing to step 4:
83 can be fit into 595 7 times, resulting in a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Subtract 581 from 595 to get 14.
Include the next digit (7) from the dividend after 14, then repeat: 147 / 83

Let's proceed to step 5:
147 divided by 83 is 1 with a remainder of 64.
The next digit of our result is 1. 
Result so far: 471.0
Subtract 83 from 147 to get 64.
Take the next digit (0) from the dividend and append it to 64, then repeat: 640 / 83

On to step 6:
83 goes into 640 7 times with a remainder of 59.
The number 7 becomes the next digit in our result. 
Result so far: 4717.0
Deduct 581 from 640 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 7:
When dividing 590 by 83, we get 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 4717.7
If we subtract 581 from 590, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 8:
83 can be fit into 90 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 4717.71
The remainder is 7 after subtracting 83 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 9:
When dividing 70 by 83, we get 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 4717.71
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 10:
83 can be fit into 700 8 times, resulting in a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 4717.7108
Deduct 664 from 700 and we're left 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.

Step 11:
When dividing 360 by 83, we get 4 with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 4717.71084
The remainder is 28 after subtracting 332 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 12:
The number 83 fits into 280 3 times, leaving a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 4717.710843
The remainder is 31 after subtracting 249 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 13:
If we divide 310 by 83, we get 3 and a remainder of 61.
Record the quotient 3 as the next digit in the result. 
Result so far: 4717.7108433
The remainder is 61 after subtracting 249 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

The final outcome is 4717.7108433, with a leftover of 6.1e-07.
