52239567 ÷ 669 
Let's see how many times 669 fits into 52239567.

Going ahead to step 1:
5 divided by 669 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 669

On to step 2:
52 divided by 669 is 0 with a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Fetch the next digit (2) from the dividend, attach it to 52 and continue: 522 / 669

Going ahead to step 3:
522 divided by 669 is 0 with a remainder of 522.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 522 leaves us with 522.
Take the next digit (3) from the dividend and append it to 522, then repeat: 5223 / 669

Moving on to step 4:
If we divide 5223 by 669, we get 7 and a remainder of 540.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 4683 from 5223 and we're left with 540.
Take the next digit (9) from the dividend and append it to 540, then repeat: 5409 / 669

Let's proceed to step 5:
If we divide 5409 by 669, we get 8 and a remainder of 57.
Write down 8 as next digit of the result. 
Result so far: 78.0
If we subtract 5352 from 5409, we get 57.
Fetch the next digit (5) from the dividend, attach it to 57 and continue: 575 / 669

Let's proceed to step 6:
669 goes into 575 0 times with a remainder of 575.
Record the quotient 0 as the next digit in the result. 
Result so far: 780.0
The remainder is 575 after subtracting 0 from 575.
Append the next digit (6) from the dividend to 575 and continue with: 5756 / 669

Moving on to step 7:
The number 669 fits into 5756 8 times, leaving a remainder of 404.
Put 8 as the next digit of the answer. 
Result so far: 7808.0
Deduct 5352 from 5756 and we're left with 404.
Include the next digit (7) from the dividend after 404, then repeat: 4047 / 669

On to step 8:
When dividing 4047 by 669, we get 6 with a remainder of 33.
Put 6 as the next digit of the answer. 
Result so far: 78086.0
The remainder is 33 after subtracting 4014 from 4047.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 9:
When dividing 330 by 669, we get 0 with a remainder of 330.
The number 0 becomes the next digit in our result. 
Result so far: 78086.0
The remainder is 330 after subtracting 0 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 10:
If we divide 3300 by 669, we get 4 and a remainder of 624.
Record the quotient 4 as the next digit in the result. 
Result so far: 78086.04
The remainder is 624 after subtracting 2676 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Step 11:
When dividing 6240 by 669, we get 9 with a remainder of 219.
The number 9 becomes the next digit in our result. 
Result so far: 78086.049
Deduct 6021 from 6240 and we're left with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Going ahead to step 12:
669 goes into 2190 3 times with a remainder of 183.
Record the quotient 3 as the next digit in the result. 
Result so far: 78086.0493
Subtract 2007 from 2190 to get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Let's proceed to step 13:
669 can be fit into 1830 2 times, resulting in a remainder of 492.
Use 2 as the next digit of our solution. 
Result so far: 78086.04932
Deduct 1338 from 1830 and we're left with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Step 14:
669 goes into 4920 7 times with a remainder of 237.
The number 7 becomes the next digit in our result. 
Result so far: 78086.049327
Subtracting 4683 from 4920 leaves us with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Advancing to step 15:
2370 divided by 669 is 3 with a remainder of 363.
Record the quotient 3 as the next digit in the result. 
Result so far: 78086.0493273
The remainder is 363 after subtracting 2007 from 2370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

On to step 16:
The number 669 fits into 3630 5 times, leaving a remainder of 285.
The number 5 becomes the next digit in our result. 
Result so far: 78086.04932735
The remainder is 285 after subtracting 3345 from 3630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

The final result is 78086.04932735 with a remainder of 2.85e-07.
