52315611 ÷ 669 
We want to figure out the number of times 52315611 can be divided by 669.

Going ahead to step 1:
When dividing 5 by 669, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 669

Let's proceed to step 2:
The number 669 fits into 52 0 times, leaving a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 52 after subtracting 0 from 52.
Fetch the next digit (3) from the dividend, attach it to 52 and continue: 523 / 669

Let's proceed to step 3:
When dividing 523 by 669, we get 0 with a remainder of 523.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 523, we end up with 523.
Bring next digit (1) of the dividend behind the 523 and repeat the process: 5231 / 669

On to step 4:
The number 669 fits into 5231 7 times, leaving a remainder of 548.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 4683 from 5231 to get 548.
Grab the next digit (5) from the dividend, add it to 548, then carry on: 5485 / 669

Advancing to step 5:
669 can be fit into 5485 8 times, resulting in a remainder of 133.
The next digit of our result is 8. 
Result so far: 78.0
Subtract 5352 from 5485 to get 133.
Take the next digit (6) from the dividend and append it to 133, then repeat: 1336 / 669

Going ahead to step 6:
The number 669 fits into 1336 1 times, leaving a remainder of 667.
The number 1 becomes the next digit in our result. 
Result so far: 781.0
Subtracting 669 from 1336 leaves us with 667.
Take the next digit (1) from the dividend and append it to 667, then repeat: 6671 / 669

Advancing to step 7:
669 goes into 6671 9 times with a remainder of 650.
Put 9 as the next digit of the answer. 
Result so far: 7819.0
Subtract 6021 from 6671 to get 650.
Append the next digit (1) from the dividend to 650 and continue with: 6501 / 669

Step 8:
6501 divided by 669 is 9 with a remainder of 480.
The number 9 becomes the next digit in our result. 
Result so far: 78199.0
The remainder is 480 after subtracting 6021 from 6501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 9:
669 goes into 4800 7 times with a remainder of 117.
Put 7 as the next digit of the answer. 
Result so far: 78199.7
The remainder is 117 after subtracting 4683 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Advancing to step 10:
If we divide 1170 by 669, we get 1 and a remainder of 501.
Use 1 as the next digit of our solution. 
Result so far: 78199.71
If we subtract 669 from 1170, we get 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Advancing to step 11:
When dividing 5010 by 669, we get 7 with a remainder of 327.
Record the quotient 7 as the next digit in the result. 
Result so far: 78199.717
If we subtract 4683 from 5010, we get 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Moving on to step 12:
669 can be fit into 3270 4 times, resulting in a remainder of 594.
The next digit of our result is 4. 
Result so far: 78199.7174
If we take 2676 away from 3270, we end up with 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

On to step 13:
669 goes into 5940 8 times with a remainder of 588.
Write down 8 as next digit of the result. 
Result so far: 78199.71748
If we take 5352 away from 5940, we end up with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Let's proceed to step 14:
The number 669 fits into 5880 8 times, leaving a remainder of 528.
The next digit of our result is 8. 
Result so far: 78199.717488
Subtracting 5352 from 5880 leaves us with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

After the division, we end up with 78199.717488 and a remainder of 5.28e-05.
