We're dividing 85817243 by 339 
We want to figure out the number of times 85817243 can be divided by 339.

Step 1:
339 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 339

Let's proceed to step 2:
When dividing 85 by 339, we get 0 with a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Grab the next digit (8) from the dividend, add it to 85, then carry on: 858 / 339

Moving on to step 3:
If we divide 858 by 339, we get 2 and a remainder of 180.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 180 after subtracting 678 from 858.
Append the next digit (1) from the dividend to 180 and continue with: 1801 / 339

On to step 4:
The number 339 fits into 1801 5 times, leaving a remainder of 106.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
The remainder is 106 after subtracting 1695 from 1801.
Fetch the next digit (7) from the dividend, attach it to 106 and continue: 1067 / 339

On to step 5:
1067 divided by 339 is 3 with a remainder of 50.
Use 3 as the next digit of our solution. 
Result so far: 253.0
Subtract 1017 from 1067 to get 50.
Bring next digit (2) of the dividend behind the 50 and repeat the process: 502 / 339

Step 6:
When dividing 502 by 339, we get 1 with a remainder of 163.
Write down 1 as next digit of the result. 
Result so far: 2531.0
Deduct 339 from 502 and we're left with 163.
Grab the next digit (4) from the dividend, add it to 163, then carry on: 1634 / 339

Let's proceed to step 7:
When dividing 1634 by 339, we get 4 with a remainder of 278.
Record the quotient 4 as the next digit in the result. 
Result so far: 25314.0
Deduct 1356 from 1634 and we're left with 278.
Bring next digit (3) of the dividend behind the 278 and repeat the process: 2783 / 339

Let's proceed to step 8:
The number 339 fits into 2783 8 times, leaving a remainder of 71.
Use 8 as the next digit of our solution. 
Result so far: 253148.0
The remainder is 71 after subtracting 2712 from 2783.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 9:
339 goes into 710 2 times with a remainder of 32.
The next digit of our result is 2. 
Result so far: 253148.2
Subtracting 678 from 710 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
320 divided by 339 is 0 with a remainder of 320.
The next digit of our result is 0. 
Result so far: 253148.2
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 11:
3200 divided by 339 is 9 with a remainder of 149.
Write down 9 as next digit of the result. 
Result so far: 253148.209
Subtract 3051 from 3200 to get 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Moving on to step 12:
339 can be fit into 1490 4 times, resulting in a remainder of 134.
The next digit of our result is 4. 
Result so far: 253148.2094
Subtracting 1356 from 1490 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Moving on to step 13:
339 goes into 1340 3 times with a remainder of 323.
Put 3 as the next digit of the answer. 
Result so far: 253148.20943
If we take 1017 away from 1340, we end up with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Moving on to step 14:
339 goes into 3230 9 times with a remainder of 179.
The number 9 becomes the next digit in our result. 
Result so far: 253148.209439
Subtract 3051 from 3230 to get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Moving on to step 15:
When dividing 1790 by 339, we get 5 with a remainder of 95.
The next digit of our result is 5. 
Result so far: 253148.2094395
Subtracting 1695 from 1790 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 16:
339 can be fit into 950 2 times, resulting in a remainder of 272.
Record the quotient 2 as the next digit in the result. 
Result so far: 253148.20943952
If we subtract 678 from 950, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

After the division, we end up with 253148.20943952 and a remainder of 2.72e-07.
