We look at the division of 3879236 by 749 
We want to divide 3879236 by 749.

Going ahead to step 1:
The number 749 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 749

On to step 2:
The number 749 fits into 38 0 times, leaving a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Include the next digit (7) from the dividend after 38, then repeat: 387 / 749

On to step 3:
749 can be fit into 387 0 times, resulting in a remainder of 387.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 387 leaves us with 387.
Append the next digit (9) from the dividend to 387 and continue with: 3879 / 749

On to step 4:
If we divide 3879 by 749, we get 5 and a remainder of 134.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 3745 from 3879 to get 134.
Fetch the next digit (2) from the dividend, attach it to 134 and continue: 1342 / 749

Let's proceed to step 5:
749 can be fit into 1342 1 times, resulting in a remainder of 593.
Write down 1 as next digit of the result. 
Result so far: 51.0
If we take 749 away from 1342, we end up with 593.
Take the next digit (3) from the dividend and append it to 593, then repeat: 5933 / 749

Step 6:
When dividing 5933 by 749, we get 7 with a remainder of 690.
Write down 7 as next digit of the result. 
Result so far: 517.0
If we take 5243 away from 5933, we end up with 690.
Bring next digit (6) of the dividend behind the 690 and repeat the process: 6906 / 749

Advancing to step 7:
When dividing 6906 by 749, we get 9 with a remainder of 165.
The number 9 becomes the next digit in our result. 
Result so far: 5179.0
Subtracting 6741 from 6906 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Moving on to step 8:
749 goes into 1650 2 times with a remainder of 152.
Record the quotient 2 as the next digit in the result. 
Result so far: 5179.2
If we take 1498 away from 1650, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 9:
749 can be fit into 1520 2 times, resulting in a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 5179.22
Subtract 1498 from 1520 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 5179.22 with a remainder of 0.022.
