71211839 ÷ 339 
We want to figure out the number of times 71211839 can be divided by 339.

Step 1:
When dividing 7 by 339, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 339

Step 2:
When dividing 71 by 339, we get 0 with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Include the next digit (2) from the dividend after 71, then repeat: 712 / 339

Let's proceed to step 3:
When dividing 712 by 339, we get 2 with a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 678 away from 712, we end up with 34.
Include the next digit (1) from the dividend after 34, then repeat: 341 / 339

Going ahead to step 4:
339 goes into 341 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 21.0
The remainder is 2 after subtracting 339 from 341.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 339

Step 5:
The number 339 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 210.0
If we take 0 away from 21, we end up with 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 339

Let's proceed to step 6:
218 divided by 339 is 0 with a remainder of 218.
Use 0 as the next digit of our solution. 
Result so far: 2100.0
If we take 0 away from 218, we end up with 218.
Take the next digit (3) from the dividend and append it to 218, then repeat: 2183 / 339

Step 7:
339 goes into 2183 6 times with a remainder of 149.
Write down 6 as next digit of the result. 
Result so far: 21006.0
Subtract 2034 from 2183 to get 149.
Take the next digit (9) from the dividend and append it to 149, then repeat: 1499 / 339

Advancing to step 8:
If we divide 1499 by 339, we get 4 and a remainder of 143.
The next digit of our result is 4. 
Result so far: 210064.0
If we subtract 1356 from 1499, we get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Let's proceed to step 9:
The number 339 fits into 1430 4 times, leaving a remainder of 74.
The next digit of our result is 4. 
Result so far: 210064.4
If we take 1356 away from 1430, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 10:
If we divide 740 by 339, we get 2 and a remainder of 62.
Write down 2 as next digit of the result. 
Result so far: 210064.42
If we take 678 away from 740, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 11:
620 divided by 339 is 1 with a remainder of 281.
The next digit of our result is 1. 
Result so far: 210064.421
Subtracting 339 from 620 leaves us with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Moving on to step 12:
The number 339 fits into 2810 8 times, leaving a remainder of 98.
Use 8 as the next digit of our solution. 
Result so far: 210064.4218
Subtracting 2712 from 2810 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 13:
The number 339 fits into 980 2 times, leaving a remainder of 302.
Write down 2 as next digit of the result. 
Result so far: 210064.42182
Deduct 678 from 980 and we're left with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Advancing to step 14:
When dividing 3020 by 339, we get 8 with a remainder of 308.
The number 8 becomes the next digit in our result. 
Result so far: 210064.421828
If we subtract 2712 from 3020, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 15:
If we divide 3080 by 339, we get 9 and a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 210064.4218289
Subtracting 3051 from 3080 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 16:
290 divided by 339 is 0 with a remainder of 290.
Record the quotient 0 as the next digit in the result. 
Result so far: 210064.4218289
Subtract 0 from 290 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

After the division, we end up with 210064.4218289 and a remainder of 2.9e-07.
