We're dividing 12100 by 29 
We're looking to find how many times 29 goes into 12100.

On to step 1:
When dividing 1 by 29, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 29

Advancing to step 2:
When dividing 12 by 29, we get 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 29

Going ahead to step 3:
When dividing 121 by 29, we get 4 with a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 116 away from 121, we end up with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 29

On to step 4:
The number 29 fits into 50 1 times, leaving a remainder of 21.
The next digit of our result is 1. 
Result so far: 41.0
If we subtract 29 from 50, we get 21.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 29

Advancing to step 5:
29 goes into 210 7 times with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 417.0
If we subtract 203 from 210, we 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.

Moving on to step 6:
29 goes into 70 2 times with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 417.2
If we subtract 58 from 70, 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 7:
29 can be fit into 120 4 times, resulting in a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 417.24
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.

Advancing to step 8:
The number 29 fits into 40 1 times, leaving a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 417.241
If we take 29 away from 40, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 9:
29 goes into 110 3 times with a remainder of 23.
The next digit of our result is 3. 
Result so far: 417.2413
If we subtract 87 from 110, we 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.

Step 10:
230 divided by 29 is 7 with a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 417.24137
If we subtract 203 from 230, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 11:
270 divided by 29 is 9 with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 417.241379
Deduct 261 from 270 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 12:
The number 29 fits into 90 3 times, leaving a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 417.2413793
If we subtract 87 from 90, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 13:
30 divided by 29 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 417.24137931
Subtracting 29 from 30 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 417.24137931, with a leftover of 1e-09.
