68725610 divided by 669 
We want to figure out the number of times 68725610 can be divided by 669.

Step 1:
6 divided by 669 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 669

Going ahead to step 2:
If we divide 68 by 669, we get 0 and a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Fetch the next digit (7) from the dividend, attach it to 68 and continue: 687 / 669

Advancing to step 3:
669 goes into 687 1 times with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 669 from 687 leaves us with 18.
Append the next digit (2) from the dividend to 18 and continue with: 182 / 669

Going ahead to step 4:
669 can be fit into 182 0 times, resulting in a remainder of 182.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 182, we end up with 182.
Fetch the next digit (5) from the dividend, attach it to 182 and continue: 1825 / 669

Let's proceed to step 5:
When dividing 1825 by 669, we get 2 with a remainder of 487.
Use 2 as the next digit of our solution. 
Result so far: 102.0
If we take 1338 away from 1825, we end up with 487.
Append the next digit (6) from the dividend to 487 and continue with: 4876 / 669

Moving on to step 6:
If we divide 4876 by 669, we get 7 and a remainder of 193.
Put 7 as the next digit of the answer. 
Result so far: 1027.0
The remainder is 193 after subtracting 4683 from 4876.
Grab the next digit (1) from the dividend, add it to 193, then carry on: 1931 / 669

Moving on to step 7:
When dividing 1931 by 669, we get 2 with a remainder of 593.
The number 2 becomes the next digit in our result. 
Result so far: 10272.0
The remainder is 593 after subtracting 1338 from 1931.
Fetch the next digit (0) from the dividend, attach it to 593 and continue: 5930 / 669

Advancing to step 8:
669 can be fit into 5930 8 times, resulting in a remainder of 578.
The number 8 becomes the next digit in our result. 
Result so far: 102728.0
The remainder is 578 after subtracting 5352 from 5930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

On to step 9:
669 goes into 5780 8 times with a remainder of 428.
The number 8 becomes the next digit in our result. 
Result so far: 102728.8
Deduct 5352 from 5780 and we're left with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Step 10:
When dividing 4280 by 669, we get 6 with a remainder of 266.
Put 6 as the next digit of the answer. 
Result so far: 102728.86
The remainder is 266 after subtracting 4014 from 4280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Moving on to step 11:
2660 divided by 669 is 3 with a remainder of 653.
The next digit of our result is 3. 
Result so far: 102728.863
Deduct 2007 from 2660 and we're left with 653.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6530, and continue the process.

Step 12:
669 can be fit into 6530 9 times, resulting in a remainder of 509.
The next digit of our result is 9. 
Result so far: 102728.8639
Subtract 6021 from 6530 to get 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Going ahead to step 13:
669 goes into 5090 7 times with a remainder of 407.
Write down 7 as next digit of the result. 
Result so far: 102728.86397
If we subtract 4683 from 5090, we get 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Advancing to step 14:
If we divide 4070 by 669, we get 6 and a remainder of 56.
The next digit of our result is 6. 
Result so far: 102728.863976
If we take 4014 away from 4070, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 15:
If we divide 560 by 669, we get 0 and a remainder of 560.
Write down 0 as next digit of the result. 
Result so far: 102728.863976
Subtract 0 from 560 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 16:
If we divide 5600 by 669, we get 8 and a remainder of 248.
The number 8 becomes the next digit in our result. 
Result so far: 102728.86397608
If we subtract 5352 from 5600, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Our division results in 102728.86397608 with a remaining 2.48e-07.
