We look at the division of 172021 by 29 
Let's see how many times 29 fits into 172021.

Going ahead to step 1:
When dividing 1 by 29, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 29

Let's proceed to step 2:
If we divide 17 by 29, we get 0 and a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 29

Moving on to step 3:
29 goes into 172 5 times with a remainder of 27.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 145 from 172 to get 27.
Bring next digit (0) of the dividend behind the 27 and repeat the process: 270 / 29

Moving on to step 4:
The number 29 fits into 270 9 times, leaving a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 59.0
Subtract 261 from 270 to get 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 29

Going ahead to step 5:
The number 29 fits into 92 3 times, leaving a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 593.0
Subtracting 87 from 92 leaves us with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 29

Step 6:
51 divided by 29 is 1 with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 5931.0
The remainder is 22 after subtracting 29 from 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
If we divide 220 by 29, we get 7 and a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 5931.7
If we take 203 away from 220, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 8:
If we divide 170 by 29, we get 5 and a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 5931.75
Subtract 145 from 170 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 9:
29 goes into 250 8 times with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 5931.758
If we subtract 232 from 250, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 10:
29 can be fit into 180 6 times, resulting in a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 5931.7586
If we take 174 away from 180, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 11:
The number 29 fits into 60 2 times, leaving a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 5931.75862
The remainder is 2 after subtracting 58 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 12:
20 divided by 29 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 5931.75862
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
If we divide 200 by 29, we get 6 and a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 5931.7586206
Subtract 174 from 200 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 14:
260 divided by 29 is 8 with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 5931.75862068
If we subtract 232 from 260, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

In conclusion, the division gives 5931.75862068 with a balance of 2.8e-08.
