391269 ÷ 74 
We want to divide 391269 by 74.

On to step 1:
74 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 74

Moving on to step 2:
If we divide 39 by 74, we get 0 and a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Take the next digit (1) from the dividend and append it to 39, then repeat: 391 / 74

Step 3:
74 goes into 391 5 times with a remainder of 21.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 21 after subtracting 370 from 391.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 74

On to step 4:
When dividing 212 by 74, we get 2 with a remainder of 64.
The next digit of our result is 2. 
Result so far: 52.0
The remainder is 64 after subtracting 148 from 212.
Bring next digit (6) of the dividend behind the 64 and repeat the process: 646 / 74

Step 5:
74 can be fit into 646 8 times, resulting in a remainder of 54.
Put 8 as the next digit of the answer. 
Result so far: 528.0
Deduct 592 from 646 and we're left with 54.
Take the next digit (9) from the dividend and append it to 54, then repeat: 549 / 74

Moving on to step 6:
If we divide 549 by 74, we get 7 and a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 5287.0
If we subtract 518 from 549, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
When dividing 310 by 74, we get 4 with a remainder of 14.
The next digit of our result is 4. 
Result so far: 5287.4
The remainder is 14 after subtracting 296 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
74 goes into 140 1 times with a remainder of 66.
Put 1 as the next digit of the answer. 
Result so far: 5287.41
Deduct 74 from 140 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 9:
660 divided by 74 is 8 with a remainder of 68.
Use 8 as the next digit of our solution. 
Result so far: 5287.418
If we take 592 away from 660, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 10:
The number 74 fits into 680 9 times, leaving a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 5287.4189
Subtract 666 from 680 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
140 divided by 74 is 1 with a remainder of 66.
Write down 1 as next digit of the result. 
Result so far: 5287.41891
Deduct 74 from 140 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 12:
74 can be fit into 660 8 times, resulting in a remainder of 68.
The next digit of our result is 8. 
Result so far: 5287.418918
Subtracting 592 from 660 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 13:
The number 74 fits into 680 9 times, leaving a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 5287.4189189
If we subtract 666 from 680, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 14:
74 goes into 140 1 times with a remainder of 66.
Put 1 as the next digit of the answer. 
Result so far: 5287.41891891
Subtracting 74 from 140 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

After the division, we end up with 5287.41891891 and a remainder of 6.6e-08.
