Let's divide 72353436 by 343
We want to figure out the number of times 72353436 can be divided by 343.

Step 1:
When dividing 7 by 343, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 343

Step 2:
The number 343 fits into 72 0 times, leaving a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Include the next digit (3) from the dividend after 72, then repeat: 723 / 343

On to step 3:
343 can be fit into 723 2 times, resulting in a remainder of 37.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 686 away from 723, we end up with 37.
Append the next digit (5) from the dividend to 37 and continue with: 375 / 343

On to step 4:
375 divided by 343 is 1 with a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 21.0
The remainder is 32 after subtracting 343 from 375.
Fetch the next digit (3) from the dividend, attach it to 32 and continue: 323 / 343

Moving on to step 5:
343 can be fit into 323 0 times, resulting in a remainder of 323.
Use 0 as the next digit of our solution. 
Result so far: 210.0
If we take 0 away from 323, we end up with 323.
Grab the next digit (4) from the dividend, add it to 323, then carry on: 3234 / 343

Moving on to step 6:
343 goes into 3234 9 times with a remainder of 147.
Use 9 as the next digit of our solution. 
Result so far: 2109.0
If we subtract 3087 from 3234, we get 147.
Fetch the next digit (3) from the dividend, attach it to 147 and continue: 1473 / 343

Step 7:
1473 divided by 343 is 4 with a remainder of 101.
The number 4 becomes the next digit in our result. 
Result so far: 21094.0
If we take 1372 away from 1473, we end up with 101.
Take the next digit (6) from the dividend and append it to 101, then repeat: 1016 / 343

On to step 8:
If we divide 1016 by 343, we get 2 and a remainder of 330.
Put 2 as the next digit of the answer. 
Result so far: 210942.0
If we take 686 away from 1016, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 9:
343 can be fit into 3300 9 times, resulting in a remainder of 213.
The number 9 becomes the next digit in our result. 
Result so far: 210942.9
The remainder is 213 after subtracting 3087 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Going ahead to step 10:
When dividing 2130 by 343, we get 6 with a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 210942.96
Subtracting 2058 from 2130 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 11:
343 goes into 720 2 times with a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 210942.962
Deduct 686 from 720 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 12:
When dividing 340 by 343, we get 0 with a remainder of 340.
Record the quotient 0 as the next digit in the result. 
Result so far: 210942.962
Deduct 0 from 340 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 13:
The number 343 fits into 3400 9 times, leaving a remainder of 313.
Put 9 as the next digit of the answer. 
Result so far: 210942.96209
Subtracting 3087 from 3400 leaves us with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Advancing to step 14:
If we divide 3130 by 343, we get 9 and a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 210942.962099
The remainder is 43 after subtracting 3087 from 3130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

The final outcome is 210942.962099, with a leftover of 4.3e-06.
