302139 divided by 74 
Let's see how many times 74 fits into 302139.

On to step 1:
If we divide 3 by 74, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 74

Going ahead to step 2:
30 divided by 74 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Include the next digit (2) from the dividend after 30, then repeat: 302 / 74

Going ahead to step 3:
302 divided by 74 is 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 296 from 302, we get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 74

Advancing to step 4:
74 can be fit into 61 0 times, resulting in a remainder of 61.
The next digit of our result is 0. 
Result so far: 40.0
Deduct 0 from 61 and we're left with 61.
Bring next digit (3) of the dividend behind the 61 and repeat the process: 613 / 74

Advancing to step 5:
When dividing 613 by 74, we get 8 with a remainder of 21.
The number 8 becomes the next digit in our result. 
Result so far: 408.0
Subtracting 592 from 613 leaves us with 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 74

Step 6:
The number 74 fits into 219 2 times, leaving a remainder of 71.
The next digit of our result is 2. 
Result so far: 4082.0
Subtracting 148 from 219 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 7:
74 goes into 710 9 times with a remainder of 44.
The number 9 becomes the next digit in our result. 
Result so far: 4082.9
Subtracting 666 from 710 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 8:
When dividing 440 by 74, we get 5 with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 4082.95
If we subtract 370 from 440, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 9:
When dividing 700 by 74, we get 9 with a remainder of 34.
Put 9 as the next digit of the answer. 
Result so far: 4082.959
Deduct 666 from 700 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 10:
If we divide 340 by 74, we get 4 and a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 4082.9594
Subtracting 296 from 340 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 11:
440 divided by 74 is 5 with a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 4082.95945
If we take 370 away from 440, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 12:
74 can be fit into 700 9 times, resulting in a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 4082.959459
The remainder is 34 after subtracting 666 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 13:
340 divided by 74 is 4 with a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 4082.9594594
If we subtract 296 from 340, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 14:
When dividing 440 by 74, we get 5 with a remainder of 70.
The next digit of our result is 5. 
Result so far: 4082.95945945
Subtract 370 from 440 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 4082.95945945, with a leftover of 7e-08.
