390641 ÷ 29 
Let's see how many times 29 fits into 390641.

Let's proceed to step 1:
If we divide 3 by 29, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 29

On to step 2:
29 can be fit into 39 1 times, resulting in a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 29 from 39 leaves us with 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 29

Going ahead to step 3:
100 divided by 29 is 3 with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 87 away from 100, we end up with 13.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 29

Moving on to step 4:
29 goes into 136 4 times with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 134.0
Deduct 116 from 136 and we're left with 20.
Grab the next digit (4) from the dividend, add it to 20, then carry on: 204 / 29

Step 5:
29 can be fit into 204 7 times, resulting in a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 1347.0
If we subtract 203 from 204, we get 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 29

Advancing to step 6:
11 divided by 29 is 0 with a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 13470.0
Subtracting 0 from 11 leaves us 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 7:
If we divide 110 by 29, we get 3 and a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 13470.3
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 8:
29 can be fit into 230 7 times, resulting in a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 13470.37
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 9:
270 divided by 29 is 9 with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 13470.379
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.

Moving on to step 10:
When dividing 90 by 29, we get 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 13470.3793
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 11:
If we divide 30 by 29, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 13470.37931
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.

Step 12:
29 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 13470.37931
If we take 0 away from 10, we end up 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.

On to step 13:
29 goes into 100 3 times with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 13470.3793103
Subtract 87 from 100 to 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.

On to step 14:
29 goes into 130 4 times with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 13470.37931034
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 outcome is 13470.37931034, with a leftover of 1.4e-08.
