39705621 divided by 339 
We're looking to find how many times 339 goes into 39705621.

On to step 1:
339 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 339

Let's proceed to step 2:
If we divide 39 by 339, we get 0 and a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Bring next digit (7) of the dividend behind the 39 and repeat the process: 397 / 339

Going ahead to step 3:
The number 339 fits into 397 1 times, leaving a remainder of 58.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 339 from 397 and we're left with 58.
Grab the next digit (0) from the dividend, add it to 58, then carry on: 580 / 339

Let's proceed to step 4:
If we divide 580 by 339, we get 1 and a remainder of 241.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 339 from 580 leaves us with 241.
Fetch the next digit (5) from the dividend, attach it to 241 and continue: 2415 / 339

Moving on to step 5:
If we divide 2415 by 339, we get 7 and a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 117.0
Subtracting 2373 from 2415 leaves us with 42.
Bring next digit (6) of the dividend behind the 42 and repeat the process: 426 / 339

Step 6:
426 divided by 339 is 1 with a remainder of 87.
Record the quotient 1 as the next digit in the result. 
Result so far: 1171.0
If we subtract 339 from 426, we get 87.
Grab the next digit (2) from the dividend, add it to 87, then carry on: 872 / 339

Advancing to step 7:
872 divided by 339 is 2 with a remainder of 194.
The number 2 becomes the next digit in our result. 
Result so far: 11712.0
The remainder is 194 after subtracting 678 from 872.
Append the next digit (1) from the dividend to 194 and continue with: 1941 / 339

Moving on to step 8:
339 goes into 1941 5 times with a remainder of 246.
The number 5 becomes the next digit in our result. 
Result so far: 117125.0
Subtracting 1695 from 1941 leaves us with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Advancing to step 9:
When dividing 2460 by 339, we get 7 with a remainder of 87.
Record the quotient 7 as the next digit in the result. 
Result so far: 117125.7
The remainder is 87 after subtracting 2373 from 2460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 10:
870 divided by 339 is 2 with a remainder of 192.
Use 2 as the next digit of our solution. 
Result so far: 117125.72
If we take 678 away from 870, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 11:
The number 339 fits into 1920 5 times, leaving a remainder of 225.
Write down 5 as next digit of the result. 
Result so far: 117125.725
If we take 1695 away from 1920, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

On to step 12:
If we divide 2250 by 339, we get 6 and a remainder of 216.
Record the quotient 6 as the next digit in the result. 
Result so far: 117125.7256
If we take 2034 away from 2250, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 13:
When dividing 2160 by 339, we get 6 with a remainder of 126.
Use 6 as the next digit of our solution. 
Result so far: 117125.72566
If we subtract 2034 from 2160, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

The final outcome is 117125.72566, with a leftover of 0.000126.
