66685309 ÷ 29 
We're looking to find how many times 29 goes into 66685309.

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.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 29

Advancing to step 2:
29 can be fit into 66 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 58 from 66 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 29

On to step 3:
The number 29 fits into 86 2 times, leaving a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
The remainder is 28 after subtracting 58 from 86.
Take the next digit (8) from the dividend and append it to 28, then repeat: 288 / 29

Step 4:
29 can be fit into 288 9 times, resulting in a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 229.0
The remainder is 27 after subtracting 261 from 288.
Grab the next digit (5) from the dividend, add it to 27, then carry on: 275 / 29

Advancing to step 5:
If we divide 275 by 29, we get 9 and a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 2299.0
The remainder is 14 after subtracting 261 from 275.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 29

Step 6:
When dividing 143 by 29, we get 4 with a remainder of 27.
Write down 4 as next digit of the result. 
Result so far: 22994.0
If we take 116 away from 143, we end up with 27.
Bring next digit (0) of the dividend behind the 27 and repeat the process: 270 / 29

Moving on to step 7:
When dividing 270 by 29, we get 9 with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 229949.0
If we subtract 261 from 270, we get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 29

Going ahead to step 8:
If we divide 99 by 29, we get 3 and a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 2299493.0
Subtract 87 from 99 to 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.

Going ahead to step 9:
120 divided by 29 is 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 2299493.4
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.

Moving on to step 10:
29 goes into 40 1 times with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 2299493.41
Subtract 29 from 40 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 11:
When dividing 110 by 29, we get 3 with a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 2299493.413
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.

Going ahead to step 12:
29 can be fit into 230 7 times, resulting in a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 2299493.4137
Subtract 203 from 230 to 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.

On to step 13:
If we divide 270 by 29, we get 9 and a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 2299493.41379
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 14:
If we divide 90 by 29, we get 3 and a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 2299493.413793
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.

Step 15:
If we divide 30 by 29, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 2299493.4137931
The remainder is 1 after subtracting 29 from 30.
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 16:
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: 2299493.4137931
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 2299493.4137931, with a leftover of 1e-08.
