We look at the division of 3978261 by 762 
Our goal is to divide 3978261 by 762.

Step 1:
3 divided by 762 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 762

Moving on to step 2:
762 can be fit into 39 0 times, resulting in a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Fetch the next digit (7) from the dividend, attach it to 39 and continue: 397 / 762

Going ahead to step 3:
When dividing 397 by 762, we get 0 with a remainder of 397.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 397 and we're left with 397.
Grab the next digit (8) from the dividend, add it to 397, then carry on: 3978 / 762

Let's proceed to step 4:
3978 divided by 762 is 5 with a remainder of 168.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 168 after subtracting 3810 from 3978.
Fetch the next digit (2) from the dividend, attach it to 168 and continue: 1682 / 762

Moving on to step 5:
When dividing 1682 by 762, we get 2 with a remainder of 158.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
If we take 1524 away from 1682, we end up with 158.
Bring next digit (6) of the dividend behind the 158 and repeat the process: 1586 / 762

Let's proceed to step 6:
762 goes into 1586 2 times with a remainder of 62.
Write down 2 as next digit of the result. 
Result so far: 522.0
If we take 1524 away from 1586, we end up with 62.
Include the next digit (1) from the dividend after 62, then repeat: 621 / 762

Going ahead to step 7:
The number 762 fits into 621 0 times, leaving a remainder of 621.
The next digit of our result is 0. 
Result so far: 5220.0
Subtracting 0 from 621 leaves us with 621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6210, and continue the process.

Advancing to step 8:
When dividing 6210 by 762, we get 8 with a remainder of 114.
Record the quotient 8 as the next digit in the result. 
Result so far: 5220.8
If we subtract 6096 from 6210, we get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 9:
1140 divided by 762 is 1 with a remainder of 378.
Record the quotient 1 as the next digit in the result. 
Result so far: 5220.81
Subtract 762 from 1140 to get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Advancing to step 10:
When dividing 3780 by 762, we get 4 with a remainder of 732.
Put 4 as the next digit of the answer. 
Result so far: 5220.814
The remainder is 732 after subtracting 3048 from 3780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

On to step 11:
7320 divided by 762 is 9 with a remainder of 462.
Record the quotient 9 as the next digit in the result. 
Result so far: 5220.8149
Subtracting 6858 from 7320 leaves us with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

On to step 12:
When dividing 4620 by 762, we get 6 with a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 5220.81496
Subtract 4572 from 4620 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:
The number 762 fits into 480 0 times, leaving a remainder of 480.
The number 0 becomes the next digit in our result. 
Result so far: 5220.81496
Subtract 0 from 480 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 14:
If we divide 4800 by 762, we get 6 and a remainder of 228.
The number 6 becomes the next digit in our result. 
Result so far: 5220.8149606
Subtracting 4572 from 4800 leaves us with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Step 15:
762 can be fit into 2280 2 times, resulting in a remainder of 756.
The next digit of our result is 2. 
Result so far: 5220.81496062
Subtracting 1524 from 2280 leaves us with 756.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7560, and continue the process.

After the division, we end up with 5220.81496062 and a remainder of 7.56e-07.
