35663790 divided by 343 
We want to figure out the number of times 35663790 can be divided by 343.

Step 1:
3 divided by 343 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 343

Advancing to step 2:
If we divide 35 by 343, we get 0 and a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Include the next digit (6) from the dividend after 35, then repeat: 356 / 343

Going ahead to step 3:
The number 343 fits into 356 1 times, leaving a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 343 from 356 and we're left with 13.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 343

Step 4:
The number 343 fits into 136 0 times, leaving a remainder of 136.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 136, we end up with 136.
Grab the next digit (3) from the dividend, add it to 136, then carry on: 1363 / 343

On to step 5:
343 can be fit into 1363 3 times, resulting in a remainder of 334.
The next digit of our result is 3. 
Result so far: 103.0
The remainder is 334 after subtracting 1029 from 1363.
Fetch the next digit (7) from the dividend, attach it to 334 and continue: 3347 / 343

Advancing to step 6:
3347 divided by 343 is 9 with a remainder of 260.
Record the quotient 9 as the next digit in the result. 
Result so far: 1039.0
If we take 3087 away from 3347, we end up with 260.
Grab the next digit (9) from the dividend, add it to 260, then carry on: 2609 / 343

Step 7:
343 can be fit into 2609 7 times, resulting in a remainder of 208.
Use 7 as the next digit of our solution. 
Result so far: 10397.0
Subtracting 2401 from 2609 leaves us with 208.
Append the next digit (0) from the dividend to 208 and continue with: 2080 / 343

Advancing to step 8:
The number 343 fits into 2080 6 times, leaving a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 103976.0
Deduct 2058 from 2080 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
If we divide 220 by 343, we get 0 and a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 103976.0
Subtract 0 from 220 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 10:
When dividing 2200 by 343, we get 6 with a remainder of 142.
The next digit of our result is 6. 
Result so far: 103976.06
If we subtract 2058 from 2200, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Let's proceed to step 11:
When dividing 1420 by 343, we get 4 with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 103976.064
If we subtract 1372 from 1420, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 12:
343 can be fit into 480 1 times, resulting in a remainder of 137.
Use 1 as the next digit of our solution. 
Result so far: 103976.0641
If we take 343 away from 480, we end up with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Step 13:
343 goes into 1370 3 times with a remainder of 341.
Use 3 as the next digit of our solution. 
Result so far: 103976.06413
The remainder is 341 after subtracting 1029 from 1370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Advancing to step 14:
If we divide 3410 by 343, we get 9 and a remainder of 323.
Record the quotient 9 as the next digit in the result. 
Result so far: 103976.064139
If we subtract 3087 from 3410, we get 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Moving on to step 15:
The number 343 fits into 3230 9 times, leaving a remainder of 143.
Use 9 as the next digit of our solution. 
Result so far: 103976.0641399
Subtract 3087 from 3230 to get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

The final outcome is 103976.0641399, with a leftover of 1.43e-06.
