We're dividing 53505068 by 343 
We want to figure out the number of times 53505068 can be divided by 343.

Advancing to step 1:
If we divide 5 by 343, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 343

Step 2:
53 divided by 343 is 0 with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Fetch the next digit (5) from the dividend, attach it to 53 and continue: 535 / 343

Step 3:
When dividing 535 by 343, we get 1 with a remainder of 192.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 192 after subtracting 343 from 535.
Append the next digit (0) from the dividend to 192 and continue with: 1920 / 343

Let's proceed to step 4:
When dividing 1920 by 343, we get 5 with a remainder of 205.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 1715 from 1920 to get 205.
Fetch the next digit (5) from the dividend, attach it to 205 and continue: 2055 / 343

Step 5:
When dividing 2055 by 343, we get 5 with a remainder of 340.
Use 5 as the next digit of our solution. 
Result so far: 155.0
If we take 1715 away from 2055, we end up with 340.
Bring next digit (0) of the dividend behind the 340 and repeat the process: 3400 / 343

Going ahead to step 6:
3400 divided by 343 is 9 with a remainder of 313.
Use 9 as the next digit of our solution. 
Result so far: 1559.0
Deduct 3087 from 3400 and we're left with 313.
Append the next digit (6) from the dividend to 313 and continue with: 3136 / 343

Advancing to step 7:
If we divide 3136 by 343, we get 9 and a remainder of 49.
Record the quotient 9 as the next digit in the result. 
Result so far: 15599.0
If we take 3087 away from 3136, we end up with 49.
Take the next digit (8) from the dividend and append it to 49, then repeat: 498 / 343

Going ahead to step 8:
498 divided by 343 is 1 with a remainder of 155.
The number 1 becomes the next digit in our result. 
Result so far: 155991.0
If we take 343 away from 498, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Let's proceed to step 9:
The number 343 fits into 1550 4 times, leaving a remainder of 178.
Write down 4 as next digit of the result. 
Result so far: 155991.4
Subtracting 1372 from 1550 leaves us with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

On to step 10:
343 goes into 1780 5 times with a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 155991.45
Subtract 1715 from 1780 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 11:
The number 343 fits into 650 1 times, leaving a remainder of 307.
Write down 1 as next digit of the result. 
Result so far: 155991.451
Subtract 343 from 650 to get 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Step 12:
If we divide 3070 by 343, we get 8 and a remainder of 326.
Use 8 as the next digit of our solution. 
Result so far: 155991.4518
Subtracting 2744 from 3070 leaves us with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

On to step 13:
343 goes into 3260 9 times with a remainder of 173.
Record the quotient 9 as the next digit in the result. 
Result so far: 155991.45189
The remainder is 173 after subtracting 3087 from 3260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Moving on to step 14:
1730 divided by 343 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 155991.451895
If we take 1715 away from 1730, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 15:
343 goes into 150 0 times with a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 155991.451895
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 16:
If we divide 1500 by 343, we get 4 and a remainder of 128.
Put 4 as the next digit of the answer. 
Result so far: 155991.45189504
If we take 1372 away from 1500, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

In conclusion, the division gives 155991.45189504 with a balance of 1.28e-07.
