We look at the division of 129030 by 74 
Our goal is to divide 129030 by 74.

On to step 1:
74 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 74

Let's proceed to step 2:
12 divided by 74 is 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 74

Moving on to step 3:
If we divide 129 by 74, we get 1 and a remainder of 55.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 74 from 129 and we're left with 55.
Take the next digit (0) from the dividend and append it to 55, then repeat: 550 / 74

Step 4:
If we divide 550 by 74, we get 7 and a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
The remainder is 32 after subtracting 518 from 550.
Include the next digit (3) from the dividend after 32, then repeat: 323 / 74

Going ahead to step 5:
The number 74 fits into 323 4 times, leaving a remainder of 27.
Record the quotient 4 as the next digit in the result. 
Result so far: 174.0
The remainder is 27 after subtracting 296 from 323.
Grab the next digit (0) from the dividend, add it to 27, then carry on: 270 / 74

Advancing to step 6:
74 goes into 270 3 times with a remainder of 48.
The next digit of our result is 3. 
Result so far: 1743.0
Subtracting 222 from 270 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 7:
The number 74 fits into 480 6 times, leaving a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 1743.6
If we subtract 444 from 480, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 8:
74 goes into 360 4 times with a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 1743.64
Deduct 296 from 360 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 9:
640 divided by 74 is 8 with a remainder of 48.
The next digit of our result is 8. 
Result so far: 1743.648
If we subtract 592 from 640, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 10:
480 divided by 74 is 6 with a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 1743.6486
If we subtract 444 from 480, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
360 divided by 74 is 4 with a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 1743.64864
Deduct 296 from 360 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 12:
640 divided by 74 is 8 with a remainder of 48.
The next digit of our result is 8. 
Result so far: 1743.648648
Subtract 592 from 640 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 13:
74 goes into 480 6 times with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 1743.6486486
The remainder is 36 after subtracting 444 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 14:
74 can be fit into 360 4 times, resulting in a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 1743.64864864
Deduct 296 from 360 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 1743.64864864, and the remainder is 6.4e-08.
