We're dividing 12258358 by 339 
We want to divide 12258358 by 339.

Moving on to step 1:
1 divided by 339 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 339

On to step 2:
12 divided by 339 is 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 339

Advancing to step 3:
339 can be fit into 122 0 times, resulting in a remainder of 122.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 122 after subtracting 0 from 122.
Include the next digit (5) from the dividend after 122, then repeat: 1225 / 339

Let's proceed to step 4:
339 can be fit into 1225 3 times, resulting in a remainder of 208.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 1017 from 1225 to get 208.
Append the next digit (8) from the dividend to 208 and continue with: 2088 / 339

On to step 5:
If we divide 2088 by 339, we get 6 and a remainder of 54.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
If we take 2034 away from 2088, we end up with 54.
Grab the next digit (3) from the dividend, add it to 54, then carry on: 543 / 339

On to step 6:
If we divide 543 by 339, we get 1 and a remainder of 204.
Write down 1 as next digit of the result. 
Result so far: 361.0
Subtract 339 from 543 to get 204.
Include the next digit (5) from the dividend after 204, then repeat: 2045 / 339

Step 7:
The number 339 fits into 2045 6 times, leaving a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 3616.0
Subtract 2034 from 2045 to get 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 339

Moving on to step 8:
339 can be fit into 118 0 times, resulting in a remainder of 118.
The number 0 becomes the next digit in our result. 
Result so far: 36160.0
If we take 0 away from 118, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

On to step 9:
When dividing 1180 by 339, we get 3 with a remainder of 163.
Put 3 as the next digit of the answer. 
Result so far: 36160.3
The remainder is 163 after subtracting 1017 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Let's proceed to step 10:
The number 339 fits into 1630 4 times, leaving a remainder of 274.
Use 4 as the next digit of our solution. 
Result so far: 36160.34
If we subtract 1356 from 1630, we get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Going ahead to step 11:
When dividing 2740 by 339, we get 8 with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 36160.348
If we take 2712 away from 2740, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 12:
339 goes into 280 0 times with a remainder of 280.
Write down 0 as next digit of the result. 
Result so far: 36160.348
Subtract 0 from 280 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 13:
If we divide 2800 by 339, we get 8 and a remainder of 88.
The next digit of our result is 8. 
Result so far: 36160.34808
Subtract 2712 from 2800 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 14:
If we divide 880 by 339, we get 2 and a remainder of 202.
Use 2 as the next digit of our solution. 
Result so far: 36160.348082
If we take 678 away from 880, we end up with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Moving on to step 15:
339 goes into 2020 5 times with a remainder of 325.
The number 5 becomes the next digit in our result. 
Result so far: 36160.3480825
Subtract 1695 from 2020 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Going ahead to step 16:
339 can be fit into 3250 9 times, resulting in a remainder of 199.
Record the quotient 9 as the next digit in the result. 
Result so far: 36160.34808259
If we take 3051 away from 3250, we end up with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

After the division, we end up with 36160.34808259 and a remainder of 1.99e-07.
