We're dividing 73149837 by 668 
Let's see how many times 668 fits into 73149837.

Let's proceed to step 1:
7 divided by 668 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 668

Step 2:
When dividing 73 by 668, we get 0 with a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Append the next digit (1) from the dividend to 73 and continue with: 731 / 668

Step 3:
731 divided by 668 is 1 with a remainder of 63.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 668 from 731 leaves us with 63.
Grab the next digit (4) from the dividend, add it to 63, then carry on: 634 / 668

Advancing to step 4:
634 divided by 668 is 0 with a remainder of 634.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 634, we end up with 634.
Grab the next digit (9) from the dividend, add it to 634, then carry on: 6349 / 668

Moving on to step 5:
6349 divided by 668 is 9 with a remainder of 337.
Put 9 as the next digit of the answer. 
Result so far: 109.0
The remainder is 337 after subtracting 6012 from 6349.
Include the next digit (8) from the dividend after 337, then repeat: 3378 / 668

Going ahead to step 6:
If we divide 3378 by 668, we get 5 and a remainder of 38.
Use 5 as the next digit of our solution. 
Result so far: 1095.0
If we take 3340 away from 3378, we end up with 38.
Fetch the next digit (3) from the dividend, attach it to 38 and continue: 383 / 668

Step 7:
The number 668 fits into 383 0 times, leaving a remainder of 383.
The number 0 becomes the next digit in our result. 
Result so far: 10950.0
Subtracting 0 from 383 leaves us with 383.
Bring next digit (7) of the dividend behind the 383 and repeat the process: 3837 / 668

Moving on to step 8:
668 goes into 3837 5 times with a remainder of 497.
Write down 5 as next digit of the result. 
Result so far: 109505.0
The remainder is 497 after subtracting 3340 from 3837.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

Moving on to step 9:
If we divide 4970 by 668, we get 7 and a remainder of 294.
Use 7 as the next digit of our solution. 
Result so far: 109505.7
If we subtract 4676 from 4970, we get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Going ahead to step 10:
When dividing 2940 by 668, we get 4 with a remainder of 268.
Use 4 as the next digit of our solution. 
Result so far: 109505.74
If we subtract 2672 from 2940, we get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Moving on to step 11:
668 can be fit into 2680 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 109505.744
If we subtract 2672 from 2680, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 109505.744, with a leftover of 0.0008.
