We look at the division of 312478 by 83 
We want to figure out the number of times 312478 can be divided by 83.

Going ahead to step 1:
When dividing 3 by 83, we get 0 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.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 83

Let's proceed to step 2:
83 can be fit into 31 0 times, resulting in a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Fetch the next digit (2) from the dividend, attach it to 31 and continue: 312 / 83

Moving on to step 3:
The number 83 fits into 312 3 times, leaving a remainder of 63.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 249 from 312 to get 63.
Grab the next digit (4) from the dividend, add it to 63, then carry on: 634 / 83

Moving on to step 4:
634 divided by 83 is 7 with a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Deduct 581 from 634 and we're left with 53.
Append the next digit (7) from the dividend to 53 and continue with: 537 / 83

Let's proceed to step 5:
537 divided by 83 is 6 with a remainder of 39.
Record the quotient 6 as the next digit in the result. 
Result so far: 376.0
Deduct 498 from 537 and we're left with 39.
Fetch the next digit (8) from the dividend, attach it to 39 and continue: 398 / 83

Let's proceed to step 6:
398 divided by 83 is 4 with a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 3764.0
Subtract 332 from 398 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 7:
660 divided by 83 is 7 with a remainder of 79.
Use 7 as the next digit of our solution. 
Result so far: 3764.7
If we take 581 away from 660, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 8:
83 can be fit into 790 9 times, resulting in a remainder of 43.
The next digit of our result is 9. 
Result so far: 3764.79
Deduct 747 from 790 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 9:
If we divide 430 by 83, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 3764.795
If we subtract 415 from 430, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
83 can be fit into 150 1 times, resulting in a remainder of 67.
The next digit of our result is 1. 
Result so far: 3764.7951
Subtracting 83 from 150 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 11:
The number 83 fits into 670 8 times, leaving a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 3764.79518
If we subtract 664 from 670, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 12:
When dividing 60 by 83, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 3764.79518
Deduct 0 from 60 and we're left 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.

Going ahead to step 13:
When dividing 600 by 83, we get 7 with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 3764.7951807
Subtracting 581 from 600 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 14:
190 divided by 83 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 3764.79518072
If we subtract 166 from 190, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 3764.79518072 with a remainder of 2.4e-08.
