Let's divide 312219 by 74
We're looking to find how many times 74 goes into 312219.

Going ahead to step 1:
If we divide 3 by 74, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 74

On to step 2:
If we divide 31 by 74, we get 0 and a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Take the next digit (2) from the dividend and append it to 31, then repeat: 312 / 74

Advancing to step 3:
74 can be fit into 312 4 times, resulting in a remainder of 16.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 296 from 312 and we're left with 16.
Grab the next digit (2) from the dividend, add it to 16, then carry on: 162 / 74

Let's proceed to step 4:
The number 74 fits into 162 2 times, leaving a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Subtract 148 from 162 to get 14.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 74

Advancing to step 5:
74 goes into 141 1 times with a remainder of 67.
The next digit of our result is 1. 
Result so far: 421.0
Subtract 74 from 141 to get 67.
Take the next digit (9) from the dividend and append it to 67, then repeat: 679 / 74

Going ahead to step 6:
74 can be fit into 679 9 times, resulting in a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 4219.0
If we take 666 away from 679, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
74 goes into 130 1 times with a remainder of 56.
Record the quotient 1 as the next digit in the result. 
Result so far: 4219.1
If we subtract 74 from 130, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 8:
560 divided by 74 is 7 with a remainder of 42.
Put 7 as the next digit of the answer. 
Result so far: 4219.17
Subtracting 518 from 560 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 9:
When dividing 420 by 74, we get 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 4219.175
The remainder is 50 after subtracting 370 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
500 divided by 74 is 6 with a remainder of 56.
The next digit of our result is 6. 
Result so far: 4219.1756
The remainder is 56 after subtracting 444 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 11:
74 can be fit into 560 7 times, resulting in a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 4219.17567
The remainder is 42 after subtracting 518 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 12:
74 goes into 420 5 times with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 4219.175675
The remainder is 50 after subtracting 370 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
When dividing 500 by 74, we get 6 with a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 4219.1756756
If we subtract 444 from 500, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 14:
560 divided by 74 is 7 with a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 4219.17567567
If we subtract 518 from 560, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

After the division, we end up with 4219.17567567 and a remainder of 4.2e-08.
