Let's divide 39642245 by 343
We're looking to find how many times 343 goes into 39642245.

On to step 1:
343 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 343

Let's proceed to step 2:
39 divided by 343 is 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Fetch the next digit (6) from the dividend, attach it to 39 and continue: 396 / 343

Step 3:
396 divided by 343 is 1 with a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 343 from 396 leaves us with 53.
Take the next digit (4) from the dividend and append it to 53, then repeat: 534 / 343

On to step 4:
If we divide 534 by 343, we get 1 and a remainder of 191.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 343 from 534 and we're left with 191.
Take the next digit (2) from the dividend and append it to 191, then repeat: 1912 / 343

Let's proceed to step 5:
1912 divided by 343 is 5 with a remainder of 197.
Put 5 as the next digit of the answer. 
Result so far: 115.0
Subtract 1715 from 1912 to get 197.
Append the next digit (2) from the dividend to 197 and continue with: 1972 / 343

Advancing to step 6:
When dividing 1972 by 343, we get 5 with a remainder of 257.
Write down 5 as next digit of the result. 
Result so far: 1155.0
If we subtract 1715 from 1972, we get 257.
Grab the next digit (4) from the dividend, add it to 257, then carry on: 2574 / 343

Advancing to step 7:
343 goes into 2574 7 times with a remainder of 173.
Put 7 as the next digit of the answer. 
Result so far: 11557.0
Subtracting 2401 from 2574 leaves us with 173.
Grab the next digit (5) from the dividend, add it to 173, then carry on: 1735 / 343

Advancing to step 8:
343 can be fit into 1735 5 times, resulting in a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 115575.0
If we take 1715 away from 1735, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
The number 343 fits into 200 0 times, leaving a remainder of 200.
The next digit of our result is 0. 
Result so far: 115575.0
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 10:
The number 343 fits into 2000 5 times, leaving a remainder of 285.
The next digit of our result is 5. 
Result so far: 115575.05
Subtracting 1715 from 2000 leaves us with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Let's proceed to step 11:
When dividing 2850 by 343, we get 8 with a remainder of 106.
Record the quotient 8 as the next digit in the result. 
Result so far: 115575.058
If we subtract 2744 from 2850, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 12:
When dividing 1060 by 343, we get 3 with a remainder of 31.
Use 3 as the next digit of our solution. 
Result so far: 115575.0583
Subtracting 1029 from 1060 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 13:
The number 343 fits into 310 0 times, leaving a remainder of 310.
Write down 0 as next digit of the result. 
Result so far: 115575.0583
Subtracting 0 from 310 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 14:
The number 343 fits into 3100 9 times, leaving a remainder of 13.
The next digit of our result is 9. 
Result so far: 115575.058309
If we subtract 3087 from 3100, 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.

Advancing to step 15:
343 can be fit into 130 0 times, resulting in a remainder of 130.
Use 0 as the next digit of our solution. 
Result so far: 115575.058309
Deduct 0 from 130 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 16:
The number 343 fits into 1300 3 times, leaving a remainder of 271.
Put 3 as the next digit of the answer. 
Result so far: 115575.05830903
The remainder is 271 after subtracting 1029 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

The final outcome is 115575.05830903, with a leftover of 2.71e-07.
