We're dividing 57107809 by 339 
We want to figure out the number of times 57107809 can be divided by 339.

Moving on to step 1:
When dividing 5 by 339, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 339

Going ahead to step 2:
339 goes into 57 0 times with a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Bring next digit (1) of the dividend behind the 57 and repeat the process: 571 / 339

Advancing to step 3:
339 goes into 571 1 times with a remainder of 232.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 339 from 571 to get 232.
Take the next digit (0) from the dividend and append it to 232, then repeat: 2320 / 339

On to step 4:
When dividing 2320 by 339, we get 6 with a remainder of 286.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Deduct 2034 from 2320 and we're left with 286.
Grab the next digit (7) from the dividend, add it to 286, then carry on: 2867 / 339

Going ahead to step 5:
If we divide 2867 by 339, we get 8 and a remainder of 155.
The next digit of our result is 8. 
Result so far: 168.0
Deduct 2712 from 2867 and we're left with 155.
Include the next digit (8) from the dividend after 155, then repeat: 1558 / 339

Moving on to step 6:
The number 339 fits into 1558 4 times, leaving a remainder of 202.
Record the quotient 4 as the next digit in the result. 
Result so far: 1684.0
Subtracting 1356 from 1558 leaves us with 202.
Grab the next digit (0) from the dividend, add it to 202, then carry on: 2020 / 339

Advancing to step 7:
The number 339 fits into 2020 5 times, leaving a remainder of 325.
Record the quotient 5 as the next digit in the result. 
Result so far: 16845.0
The remainder is 325 after subtracting 1695 from 2020.
Grab the next digit (9) from the dividend, add it to 325, then carry on: 3259 / 339

Step 8:
The number 339 fits into 3259 9 times, leaving a remainder of 208.
Use 9 as the next digit of our solution. 
Result so far: 168459.0
If we subtract 3051 from 3259, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 9:
When dividing 2080 by 339, we get 6 with a remainder of 46.
Record the quotient 6 as the next digit in the result. 
Result so far: 168459.6
Subtract 2034 from 2080 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 10:
339 can be fit into 460 1 times, resulting in a remainder of 121.
Record the quotient 1 as the next digit in the result. 
Result so far: 168459.61
Subtracting 339 from 460 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

On to step 11:
339 goes into 1210 3 times with a remainder of 193.
Write down 3 as next digit of the result. 
Result so far: 168459.613
Subtracting 1017 from 1210 leaves us with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

On to step 12:
If we divide 1930 by 339, we get 5 and a remainder of 235.
The number 5 becomes the next digit in our result. 
Result so far: 168459.6135
If we take 1695 away from 1930, we end up with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Step 13:
The number 339 fits into 2350 6 times, leaving a remainder of 316.
Record the quotient 6 as the next digit in the result. 
Result so far: 168459.61356
If we subtract 2034 from 2350, we get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 14:
339 can be fit into 3160 9 times, resulting in a remainder of 109.
Put 9 as the next digit of the answer. 
Result so far: 168459.613569
Subtract 3051 from 3160 to get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Let's proceed to step 15:
339 goes into 1090 3 times with a remainder of 73.
The next digit of our result is 3. 
Result so far: 168459.6135693
The remainder is 73 after subtracting 1017 from 1090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 16:
339 can be fit into 730 2 times, resulting in a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 168459.61356932
If we take 678 away from 730, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final result is 168459.61356932 with a remainder of 5.2e-08.
