We're dividing 120239 by 29 
We want to figure out the number of times 120239 can be divided by 29.

Step 1:
1 divided by 29 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 29

Moving on to step 2:
12 divided by 29 is 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 29

Advancing to step 3:
If we divide 120 by 29, we get 4 and a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 116 from 120 leaves us with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 29

On to step 4:
42 divided by 29 is 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
If we subtract 29 from 42, we get 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 29

Advancing to step 5:
The number 29 fits into 133 4 times, leaving a remainder of 17.
The next digit of our result is 4. 
Result so far: 414.0
Deduct 116 from 133 and we're left with 17.
Bring next digit (9) of the dividend behind the 17 and repeat the process: 179 / 29

On to step 6:
29 goes into 179 6 times with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 4146.0
If we subtract 174 from 179, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
50 divided by 29 is 1 with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 4146.1
Deduct 29 from 50 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 8:
The number 29 fits into 210 7 times, leaving a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 4146.17
Subtract 203 from 210 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
If we divide 70 by 29, we get 2 and a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 4146.172
Deduct 58 from 70 and we're left 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.

Step 10:
The number 29 fits into 120 4 times, leaving a remainder of 4.
The next digit of our result is 4. 
Result so far: 4146.1724
Subtracting 116 from 120 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
40 divided by 29 is 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 4146.17241
The remainder is 11 after subtracting 29 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 12:
110 divided by 29 is 3 with a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 4146.172413
Subtract 87 from 110 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 13:
When dividing 230 by 29, we get 7 with a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 4146.1724137
Subtracting 203 from 230 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 14:
If we divide 270 by 29, we get 9 and a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 4146.17241379
Subtract 261 from 270 to 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.

Our division results in 4146.17241379 with a remaining 9e-09.
