We look at the division of 339888 by 51 
Our goal is to divide 339888 by 51.

Let's proceed to step 1:
51 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 51

Going ahead to step 2:
When dividing 33 by 51, we get 0 with a remainder of 33.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 33, we end up with 33.
Grab the next digit (9) from the dividend, add it to 33, then carry on: 339 / 51

Going ahead to step 3:
When dividing 339 by 51, we get 6 with a remainder of 33.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 306 from 339, we get 33.
Append the next digit (8) from the dividend to 33 and continue with: 338 / 51

Advancing to step 4:
338 divided by 51 is 6 with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 66.0
Subtract 306 from 338 to get 32.
Take the next digit (8) from the dividend and append it to 32, then repeat: 328 / 51

Advancing to step 5:
When dividing 328 by 51, we get 6 with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 666.0
Deduct 306 from 328 and we're left with 22.
Fetch the next digit (8) from the dividend, attach it to 22 and continue: 228 / 51

Going ahead to step 6:
51 goes into 228 4 times with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 6664.0
The remainder is 24 after subtracting 204 from 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 7:
When dividing 240 by 51, we get 4 with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 6664.4
Deduct 204 from 240 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 8:
51 goes into 360 7 times with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 6664.47
Deduct 357 from 360 and we're left 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.

Step 9:
51 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 6664.47
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
When dividing 300 by 51, we get 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 6664.4705
Subtract 255 from 300 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 11:
The number 51 fits into 450 8 times, leaving a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 6664.47058
If we subtract 408 from 450, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 12:
If we divide 420 by 51, we get 8 and a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 6664.470588
Deduct 408 from 420 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 6664.470588 with a balance of 1.2e-06.
