39759354 divided by 339 
We want to divide 39759354 by 339.

Advancing to step 1:
3 divided by 339 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 339

Going ahead to step 2:
39 divided by 339 is 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Include the next digit (7) from the dividend after 39, then repeat: 397 / 339

Advancing to step 3:
339 goes into 397 1 times with a remainder of 58.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 339 from 397 and we're left with 58.
Include the next digit (5) from the dividend after 58, then repeat: 585 / 339

Step 4:
If we divide 585 by 339, we get 1 and a remainder of 246.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 339 from 585 and we're left with 246.
Take the next digit (9) from the dividend and append it to 246, then repeat: 2469 / 339

Moving on to step 5:
339 goes into 2469 7 times with a remainder of 96.
Record the quotient 7 as the next digit in the result. 
Result so far: 117.0
The remainder is 96 after subtracting 2373 from 2469.
Append the next digit (3) from the dividend to 96 and continue with: 963 / 339

On to step 6:
339 goes into 963 2 times with a remainder of 285.
The number 2 becomes the next digit in our result. 
Result so far: 1172.0
Subtract 678 from 963 to get 285.
Grab the next digit (5) from the dividend, add it to 285, then carry on: 2855 / 339

Step 7:
339 goes into 2855 8 times with a remainder of 143.
Use 8 as the next digit of our solution. 
Result so far: 11728.0
Subtracting 2712 from 2855 leaves us with 143.
Grab the next digit (4) from the dividend, add it to 143, then carry on: 1434 / 339

Moving on to step 8:
When dividing 1434 by 339, we get 4 with a remainder of 78.
The number 4 becomes the next digit in our result. 
Result so far: 117284.0
If we take 1356 away from 1434, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 9:
780 divided by 339 is 2 with a remainder of 102.
Use 2 as the next digit of our solution. 
Result so far: 117284.2
If we take 678 away from 780, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Step 10:
339 goes into 1020 3 times with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 117284.23
Subtracting 1017 from 1020 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 11:
If we divide 30 by 339, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 117284.23
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
The number 339 fits into 300 0 times, leaving a remainder of 300.
The next digit of our result is 0. 
Result so far: 117284.23
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

After the division, we end up with 117284.23 and a remainder of 0.003.
