45120109 divided by 343 
Let's see how many times 343 fits into 45120109.

On to step 1:
The number 343 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 343

Going ahead to step 2:
45 divided by 343 is 0 with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Take the next digit (1) from the dividend and append it to 45, then repeat: 451 / 343

On to step 3:
451 divided by 343 is 1 with a remainder of 108.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 343 from 451 and we're left with 108.
Grab the next digit (2) from the dividend, add it to 108, then carry on: 1082 / 343

On to step 4:
343 can be fit into 1082 3 times, resulting in a remainder of 53.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 1029 from 1082, we get 53.
Take the next digit (0) from the dividend and append it to 53, then repeat: 530 / 343

Moving on to step 5:
530 divided by 343 is 1 with a remainder of 187.
Write down 1 as next digit of the result. 
Result so far: 131.0
Subtract 343 from 530 to get 187.
Fetch the next digit (1) from the dividend, attach it to 187 and continue: 1871 / 343

Step 6:
1871 divided by 343 is 5 with a remainder of 156.
Write down 5 as next digit of the result. 
Result so far: 1315.0
Subtract 1715 from 1871 to get 156.
Grab the next digit (0) from the dividend, add it to 156, then carry on: 1560 / 343

Step 7:
1560 divided by 343 is 4 with a remainder of 188.
Record the quotient 4 as the next digit in the result. 
Result so far: 13154.0
The remainder is 188 after subtracting 1372 from 1560.
Take the next digit (9) from the dividend and append it to 188, then repeat: 1889 / 343

Let's proceed to step 8:
If we divide 1889 by 343, we get 5 and a remainder of 174.
Record the quotient 5 as the next digit in the result. 
Result so far: 131545.0
If we take 1715 away from 1889, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Step 9:
343 goes into 1740 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 131545.5
Subtracting 1715 from 1740 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 10:
250 divided by 343 is 0 with a remainder of 250.
The next digit of our result is 0. 
Result so far: 131545.5
If we subtract 0 from 250, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 11:
343 can be fit into 2500 7 times, resulting in a remainder of 99.
Use 7 as the next digit of our solution. 
Result so far: 131545.507
If we take 2401 away from 2500, we end up with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

On to step 12:
The number 343 fits into 990 2 times, leaving a remainder of 304.
The number 2 becomes the next digit in our result. 
Result so far: 131545.5072
If we take 686 away from 990, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Going ahead to step 13:
343 goes into 3040 8 times with a remainder of 296.
Write down 8 as next digit of the result. 
Result so far: 131545.50728
Subtracting 2744 from 3040 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Step 14:
343 can be fit into 2960 8 times, resulting in a remainder of 216.
Write down 8 as next digit of the result. 
Result so far: 131545.507288
Subtract 2744 from 2960 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

In conclusion, the division gives 131545.507288 with a balance of 2.16e-05.
