638906 ÷ 29 
We're looking to find how many times 29 goes into 638906.

Moving on to step 1:
The number 29 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 29

On to step 2:
29 goes into 63 2 times with a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 58 from 63 to get 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 29

Moving on to step 3:
29 can be fit into 58 2 times, resulting in a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Deduct 58 from 58 and we're left with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 29

Advancing to step 4:
29 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 220.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 29

Going ahead to step 5:
29 can be fit into 90 3 times, resulting in a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 2203.0
Deduct 87 from 90 and we're left with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 29

Moving on to step 6:
29 can be fit into 36 1 times, resulting in a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 22031.0
If we subtract 29 from 36, 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.

Going ahead to step 7:
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: 22031.2
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.

Advancing to step 8:
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: 22031.24
If we subtract 116 from 120, we get 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 9:
If we divide 40 by 29, we get 1 and a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 22031.241
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 10:
29 goes into 110 3 times with a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 22031.2413
Deduct 87 from 110 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 11:
29 goes into 230 7 times with a remainder of 27.
The next digit of our result is 7. 
Result so far: 22031.24137
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.

Going ahead to step 12:
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: 22031.241379
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.

Let's proceed to step 13:
The number 29 fits into 90 3 times, leaving a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 22031.2413793
Subtract 87 from 90 to 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.

Let's proceed to step 14:
The number 29 fits into 30 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 22031.24137931
Subtract 29 from 30 to get 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 22031.24137931, with a leftover of 1e-09.
