We look at the division of 75472800 by 669 
We want to figure out the number of times 75472800 can be divided by 669.

Step 1:
When dividing 7 by 669, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 669

Going ahead to step 2:
75 divided by 669 is 0 with a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Fetch the next digit (4) from the dividend, attach it to 75 and continue: 754 / 669

Going ahead to step 3:
When dividing 754 by 669, we get 1 with a remainder of 85.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 85 after subtracting 669 from 754.
Append the next digit (7) from the dividend to 85 and continue with: 857 / 669

Step 4:
If we divide 857 by 669, we get 1 and a remainder of 188.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 669 from 857 to get 188.
Bring next digit (2) of the dividend behind the 188 and repeat the process: 1882 / 669

On to step 5:
1882 divided by 669 is 2 with a remainder of 544.
Put 2 as the next digit of the answer. 
Result so far: 112.0
If we take 1338 away from 1882, we end up with 544.
Include the next digit (8) from the dividend after 544, then repeat: 5448 / 669

Advancing to step 6:
The number 669 fits into 5448 8 times, leaving a remainder of 96.
The number 8 becomes the next digit in our result. 
Result so far: 1128.0
Subtracting 5352 from 5448 leaves us with 96.
Fetch the next digit (0) from the dividend, attach it to 96 and continue: 960 / 669

Step 7:
669 can be fit into 960 1 times, resulting in a remainder of 291.
Record the quotient 1 as the next digit in the result. 
Result so far: 11281.0
If we take 669 away from 960, we end up with 291.
Grab the next digit (0) from the dividend, add it to 291, then carry on: 2910 / 669

Let's proceed to step 8:
669 can be fit into 2910 4 times, resulting in a remainder of 234.
Record the quotient 4 as the next digit in the result. 
Result so far: 112814.0
The remainder is 234 after subtracting 2676 from 2910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

On to step 9:
669 can be fit into 2340 3 times, resulting in a remainder of 333.
Use 3 as the next digit of our solution. 
Result so far: 112814.3
If we subtract 2007 from 2340, we get 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Advancing to step 10:
If we divide 3330 by 669, we get 4 and a remainder of 654.
Put 4 as the next digit of the answer. 
Result so far: 112814.34
The remainder is 654 after subtracting 2676 from 3330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Advancing to step 11:
669 can be fit into 6540 9 times, resulting in a remainder of 519.
Write down 9 as next digit of the result. 
Result so far: 112814.349
Subtracting 6021 from 6540 leaves us with 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

On to step 12:
669 goes into 5190 7 times with a remainder of 507.
Use 7 as the next digit of our solution. 
Result so far: 112814.3497
The remainder is 507 after subtracting 4683 from 5190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Going ahead to step 13:
When dividing 5070 by 669, we get 7 with a remainder of 387.
The next digit of our result is 7. 
Result so far: 112814.34977
If we take 4683 away from 5070, we end up with 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

The quotient of the division is 112814.34977, and the remainder is 0.000387.
