We look at the division of 42644838 by 312 
Our goal is to divide 42644838 by 312.

Advancing to step 1:
The number 312 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 312

Step 2:
If we divide 42 by 312, we get 0 and a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Append the next digit (6) from the dividend to 42 and continue with: 426 / 312

Moving on to step 3:
The number 312 fits into 426 1 times, leaving a remainder of 114.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 312 from 426 to get 114.
Include the next digit (4) from the dividend after 114, then repeat: 1144 / 312

On to step 4:
1144 divided by 312 is 3 with a remainder of 208.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 936 away from 1144, we end up with 208.
Bring next digit (4) of the dividend behind the 208 and repeat the process: 2084 / 312

Moving on to step 5:
2084 divided by 312 is 6 with a remainder of 212.
Write down 6 as next digit of the result. 
Result so far: 136.0
If we take 1872 away from 2084, we end up with 212.
Bring next digit (8) of the dividend behind the 212 and repeat the process: 2128 / 312

Let's proceed to step 6:
The number 312 fits into 2128 6 times, leaving a remainder of 256.
The next digit of our result is 6. 
Result so far: 1366.0
Subtract 1872 from 2128 to get 256.
Fetch the next digit (3) from the dividend, attach it to 256 and continue: 2563 / 312

Advancing to step 7:
If we divide 2563 by 312, we get 8 and a remainder of 67.
The number 8 becomes the next digit in our result. 
Result so far: 13668.0
If we subtract 2496 from 2563, we get 67.
Grab the next digit (8) from the dividend, add it to 67, then carry on: 678 / 312

Step 8:
When dividing 678 by 312, we get 2 with a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 136682.0
Subtracting 624 from 678 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 9:
If we divide 540 by 312, we get 1 and a remainder of 228.
Write down 1 as next digit of the result. 
Result so far: 136682.1
Subtract 312 from 540 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Advancing to step 10:
If we divide 2280 by 312, we get 7 and a remainder of 96.
The number 7 becomes the next digit in our result. 
Result so far: 136682.17
Deduct 2184 from 2280 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 11:
312 goes into 960 3 times with a remainder of 24.
The next digit of our result is 3. 
Result so far: 136682.173
Subtract 936 from 960 to 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.

Moving on to step 12:
240 divided by 312 is 0 with a remainder of 240.
The next digit of our result is 0. 
Result so far: 136682.173
Subtracting 0 from 240 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 13:
The number 312 fits into 2400 7 times, leaving a remainder of 216.
Write down 7 as next digit of the result. 
Result so far: 136682.17307
The remainder is 216 after subtracting 2184 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 14:
312 can be fit into 2160 6 times, resulting in a remainder of 288.
The next digit of our result is 6. 
Result so far: 136682.173076
Subtract 1872 from 2160 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 15:
When dividing 2880 by 312, we get 9 with a remainder of 72.
The number 9 becomes the next digit in our result. 
Result so far: 136682.1730769
Subtracting 2808 from 2880 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 16:
720 divided by 312 is 2 with a remainder of 96.
Write down 2 as next digit of the result. 
Result so far: 136682.17307692
Deduct 624 from 720 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

In conclusion, the division gives 136682.17307692 with a balance of 9.6e-08.
