We're dividing 39381283 by 458 
Our goal is to divide 39381283 by 458.

Let's proceed to step 1:
When dividing 3 by 458, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
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 / 458

Let's proceed to step 2:
458 goes into 39 0 times with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 458

Going ahead to step 3:
When dividing 393 by 458, we get 0 with a remainder of 393.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 393, we end up with 393.
Bring next digit (8) of the dividend behind the 393 and repeat the process: 3938 / 458

On to step 4:
458 goes into 3938 8 times with a remainder of 274.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 3664 from 3938 and we're left with 274.
Bring next digit (1) of the dividend behind the 274 and repeat the process: 2741 / 458

Advancing to step 5:
458 goes into 2741 5 times with a remainder of 451.
Use 5 as the next digit of our solution. 
Result so far: 85.0
The remainder is 451 after subtracting 2290 from 2741.
Include the next digit (2) from the dividend after 451, then repeat: 4512 / 458

Step 6:
If we divide 4512 by 458, we get 9 and a remainder of 390.
The next digit of our result is 9. 
Result so far: 859.0
Subtracting 4122 from 4512 leaves us with 390.
Grab the next digit (8) from the dividend, add it to 390, then carry on: 3908 / 458

Moving on to step 7:
The number 458 fits into 3908 8 times, leaving a remainder of 244.
Write down 8 as next digit of the result. 
Result so far: 8598.0
Deduct 3664 from 3908 and we're left with 244.
Bring next digit (3) of the dividend behind the 244 and repeat the process: 2443 / 458

Going ahead to step 8:
If we divide 2443 by 458, we get 5 and a remainder of 153.
Record the quotient 5 as the next digit in the result. 
Result so far: 85985.0
The remainder is 153 after subtracting 2290 from 2443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

On to step 9:
1530 divided by 458 is 3 with a remainder of 156.
The next digit of our result is 3. 
Result so far: 85985.3
Deduct 1374 from 1530 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 10:
If we divide 1560 by 458, we get 3 and a remainder of 186.
Put 3 as the next digit of the answer. 
Result so far: 85985.33
Subtracting 1374 from 1560 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

The quotient of the division is 85985.33, and the remainder is 0.186.
