42918553 divided by 312 
Let's see how many times 312 fits into 42918553.

On to step 1:
If we divide 4 by 312, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 312

Moving on to step 2:
When dividing 42 by 312, we get 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Bring next digit (9) of the dividend behind the 42 and repeat the process: 429 / 312

Let's proceed to step 3:
429 divided by 312 is 1 with a remainder of 117.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 312 from 429 leaves us with 117.
Bring next digit (1) of the dividend behind the 117 and repeat the process: 1171 / 312

Advancing to step 4:
If we divide 1171 by 312, we get 3 and a remainder of 235.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 936 from 1171 to get 235.
Include the next digit (8) from the dividend after 235, then repeat: 2358 / 312

Step 5:
312 goes into 2358 7 times with a remainder of 174.
Use 7 as the next digit of our solution. 
Result so far: 137.0
Subtract 2184 from 2358 to get 174.
Include the next digit (5) from the dividend after 174, then repeat: 1745 / 312

Advancing to step 6:
The number 312 fits into 1745 5 times, leaving a remainder of 185.
The next digit of our result is 5. 
Result so far: 1375.0
Subtract 1560 from 1745 to get 185.
Take the next digit (5) from the dividend and append it to 185, then repeat: 1855 / 312

Moving on to step 7:
312 goes into 1855 5 times with a remainder of 295.
Put 5 as the next digit of the answer. 
Result so far: 13755.0
If we take 1560 away from 1855, we end up with 295.
Append the next digit (3) from the dividend to 295 and continue with: 2953 / 312

On to step 8:
312 can be fit into 2953 9 times, resulting in a remainder of 145.
Record the quotient 9 as the next digit in the result. 
Result so far: 137559.0
Deduct 2808 from 2953 and we're left with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

On to step 9:
312 can be fit into 1450 4 times, resulting in a remainder of 202.
Write down 4 as next digit of the result. 
Result so far: 137559.4
If we take 1248 away from 1450, we end up with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Moving on to step 10:
2020 divided by 312 is 6 with a remainder of 148.
The next digit of our result is 6. 
Result so far: 137559.46
Subtract 1872 from 2020 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 11:
The number 312 fits into 1480 4 times, leaving a remainder of 232.
Record the quotient 4 as the next digit in the result. 
Result so far: 137559.464
If we subtract 1248 from 1480, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 12:
If we divide 2320 by 312, we get 7 and a remainder of 136.
Write down 7 as next digit of the result. 
Result so far: 137559.4647
Subtracting 2184 from 2320 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 13:
1360 divided by 312 is 4 with a remainder of 112.
The next digit of our result is 4. 
Result so far: 137559.46474
Subtract 1248 from 1360 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 14:
The number 312 fits into 1120 3 times, leaving a remainder of 184.
The next digit of our result is 3. 
Result so far: 137559.464743
Deduct 936 from 1120 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 15:
If we divide 1840 by 312, we get 5 and a remainder of 280.
Record the quotient 5 as the next digit in the result. 
Result so far: 137559.4647435
Subtract 1560 from 1840 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 16:
If we divide 2800 by 312, we get 8 and a remainder of 304.
Write down 8 as next digit of the result. 
Result so far: 137559.46474358
Deduct 2496 from 2800 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Our division results in 137559.46474358 with a remaining 3.04e-07.
