We look at the division of 73458648 by 669 
Let's see how many times 669 fits into 73458648.

Advancing to step 1:
669 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 669

Step 2:
669 goes into 73 0 times with a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Fetch the next digit (4) from the dividend, attach it to 73 and continue: 734 / 669

Step 3:
669 goes into 734 1 times with a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 669 from 734 leaves us with 65.
Append the next digit (5) from the dividend to 65 and continue with: 655 / 669

Let's proceed to step 4:
The number 669 fits into 655 0 times, leaving a remainder of 655.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 655, we get 655.
Take the next digit (8) from the dividend and append it to 655, then repeat: 6558 / 669

Let's proceed to step 5:
If we divide 6558 by 669, we get 9 and a remainder of 537.
Put 9 as the next digit of the answer. 
Result so far: 109.0
If we take 6021 away from 6558, we end up with 537.
Bring next digit (6) of the dividend behind the 537 and repeat the process: 5376 / 669

Going ahead to step 6:
669 can be fit into 5376 8 times, resulting in a remainder of 24.
The next digit of our result is 8. 
Result so far: 1098.0
If we subtract 5352 from 5376, we get 24.
Append the next digit (4) from the dividend to 24 and continue with: 244 / 669

Going ahead to step 7:
669 goes into 244 0 times with a remainder of 244.
Put 0 as the next digit of the answer. 
Result so far: 10980.0
If we take 0 away from 244, we end up with 244.
Bring next digit (8) of the dividend behind the 244 and repeat the process: 2448 / 669

Moving on to step 8:
669 can be fit into 2448 3 times, resulting in a remainder of 441.
Use 3 as the next digit of our solution. 
Result so far: 109803.0
Deduct 2007 from 2448 and we're left with 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Moving on to step 9:
4410 divided by 669 is 6 with a remainder of 396.
The next digit of our result is 6. 
Result so far: 109803.6
Subtract 4014 from 4410 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

On to step 10:
When dividing 3960 by 669, we get 5 with a remainder of 615.
Record the quotient 5 as the next digit in the result. 
Result so far: 109803.65
Subtracting 3345 from 3960 leaves us with 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Going ahead to step 11:
6150 divided by 669 is 9 with a remainder of 129.
Put 9 as the next digit of the answer. 
Result so far: 109803.659
If we subtract 6021 from 6150, we get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Moving on to step 12:
669 can be fit into 1290 1 times, resulting in a remainder of 621.
Record the quotient 1 as the next digit in the result. 
Result so far: 109803.6591
Deduct 669 from 1290 and we're left with 621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6210, and continue the process.

Advancing to step 13:
669 can be fit into 6210 9 times, resulting in a remainder of 189.
The number 9 becomes the next digit in our result. 
Result so far: 109803.65919
If we take 6021 away from 6210, we end up with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Advancing to step 14:
The number 669 fits into 1890 2 times, leaving a remainder of 552.
Record the quotient 2 as the next digit in the result. 
Result so far: 109803.659192
Subtract 1338 from 1890 to get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Moving on to step 15:
If we divide 5520 by 669, we get 8 and a remainder of 168.
Put 8 as the next digit of the answer. 
Result so far: 109803.6591928
Subtract 5352 from 5520 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 16:
If we divide 1680 by 669, we get 2 and a remainder of 342.
Use 2 as the next digit of our solution. 
Result so far: 109803.65919282
The remainder is 342 after subtracting 1338 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

The final result is 109803.65919282 with a remainder of 3.42e-07.
