We're dividing 74074042 by 312 
Our goal is to divide 74074042 by 312.

Let's proceed to step 1:
If we divide 7 by 312, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 312

On to step 2:
312 can be fit into 74 0 times, resulting in a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Include the next digit (0) from the dividend after 74, then repeat: 740 / 312

Advancing to step 3:
740 divided by 312 is 2 with a remainder of 116.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 624 from 740 to get 116.
Bring next digit (7) of the dividend behind the 116 and repeat the process: 1167 / 312

Advancing to step 4:
1167 divided by 312 is 3 with a remainder of 231.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtract 936 from 1167 to get 231.
Fetch the next digit (4) from the dividend, attach it to 231 and continue: 2314 / 312

Let's proceed to step 5:
2314 divided by 312 is 7 with a remainder of 130.
Put 7 as the next digit of the answer. 
Result so far: 237.0
If we subtract 2184 from 2314, we get 130.
Fetch the next digit (0) from the dividend, attach it to 130 and continue: 1300 / 312

On to step 6:
312 goes into 1300 4 times with a remainder of 52.
The next digit of our result is 4. 
Result so far: 2374.0
If we subtract 1248 from 1300, we get 52.
Append the next digit (4) from the dividend to 52 and continue with: 524 / 312

Moving on to step 7:
The number 312 fits into 524 1 times, leaving a remainder of 212.
The next digit of our result is 1. 
Result so far: 23741.0
The remainder is 212 after subtracting 312 from 524.
Append the next digit (2) from the dividend to 212 and continue with: 2122 / 312

On to step 8:
312 can be fit into 2122 6 times, resulting in a remainder of 250.
Write down 6 as next digit of the result. 
Result so far: 237416.0
Subtract 1872 from 2122 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 9:
312 can be fit into 2500 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 237416.8
The remainder is 4 after subtracting 2496 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
The number 312 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 237416.8
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
312 can be fit into 400 1 times, resulting in a remainder of 88.
Record the quotient 1 as the next digit in the result. 
Result so far: 237416.801
If we subtract 312 from 400, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 12:
If we divide 880 by 312, we get 2 and a remainder of 256.
The next digit of our result is 2. 
Result so far: 237416.8012
Subtract 624 from 880 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 13:
312 can be fit into 2560 8 times, resulting in a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 237416.80128
The remainder is 64 after subtracting 2496 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 14:
312 goes into 640 2 times with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 237416.801282
The remainder is 16 after subtracting 624 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 15:
If we divide 160 by 312, we get 0 and a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 237416.801282
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 16:
1600 divided by 312 is 5 with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 237416.80128205
The remainder is 40 after subtracting 1560 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 237416.80128205 with a remaining 4e-08.
