53139 ÷ 29 
We want to figure out the number of times 53139 can be divided by 29.

Advancing to step 1:
The number 29 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 29

Let's proceed to step 2:
29 goes into 53 1 times with a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 29 from 53 and we're left with 24.
Grab the next digit (1) from the dividend, add it to 24, then carry on: 241 / 29

Going ahead to step 3:
If we divide 241 by 29, we get 8 and a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtract 232 from 241 to get 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 29

Going ahead to step 4:
The number 29 fits into 93 3 times, leaving a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 183.0
The remainder is 6 after subtracting 87 from 93.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 29

Moving on to step 5:
If we divide 69 by 29, we get 2 and a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 1832.0
If we take 58 away from 69, 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.

On to step 6:
29 can be fit into 110 3 times, resulting in a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 1832.3
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.

Let's proceed to step 7:
When dividing 230 by 29, we get 7 with a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 1832.37
The remainder is 27 after subtracting 203 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 8:
If we divide 270 by 29, we get 9 and a remainder of 9.
The next digit of our result is 9. 
Result so far: 1832.379
Subtracting 261 from 270 leaves us 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 9:
90 divided by 29 is 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 1832.3793
Deduct 87 from 90 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 10:
30 divided by 29 is 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1832.37931
If we take 29 away from 30, we end up 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.

Moving on to step 11:
29 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1832.37931
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
29 can be fit into 100 3 times, resulting in a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 1832.3793103
If we subtract 87 from 100, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 13:
The number 29 fits into 130 4 times, leaving a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 1832.37931034
Subtract 116 from 130 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 1832.37931034 with a remainder of 1.4e-08.
