We look at the division of 139129 by 74 
We're looking to find how many times 74 goes into 139129.

Let's proceed to step 1:
74 goes into 1 0 times with 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.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 74

Let's proceed to step 2:
74 goes into 13 0 times with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 74

Moving on to step 3:
139 divided by 74 is 1 with a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 74 from 139 leaves us with 65.
Bring next digit (1) of the dividend behind the 65 and repeat the process: 651 / 74

Let's proceed to step 4:
The number 74 fits into 651 8 times, leaving a remainder of 59.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we take 592 away from 651, we end up with 59.
Take the next digit (2) from the dividend and append it to 59, then repeat: 592 / 74

On to step 5:
74 can be fit into 592 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 188.0
Deduct 592 from 592 and we're left with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 74

Advancing to step 6:
74 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 1880.0
If we subtract 0 from 9, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
74 goes into 90 1 times with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 1880.1
Deduct 74 from 90 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
When dividing 160 by 74, we get 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 1880.12
The remainder is 12 after subtracting 148 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
74 goes into 120 1 times with a remainder of 46.
Use 1 as the next digit of our solution. 
Result so far: 1880.121
If we take 74 away from 120, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 10:
If we divide 460 by 74, we get 6 and a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 1880.1216
Subtract 444 from 460 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
74 can be fit into 160 2 times, resulting in a remainder of 12.
The next digit of our result is 2. 
Result so far: 1880.12162
If we subtract 148 from 160, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
74 can be fit into 120 1 times, resulting in a remainder of 46.
Write down 1 as next digit of the result. 
Result so far: 1880.121621
The remainder is 46 after subtracting 74 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 13:
74 goes into 460 6 times with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 1880.1216216
The remainder is 16 after subtracting 444 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 14:
160 divided by 74 is 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 1880.12162162
If we take 148 away from 160, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 1880.12162162, and the remainder is 1.2e-08.
