We look at the division of 19540196 by 666 
We want to figure out the number of times 19540196 can be divided by 666.

Step 1:
666 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 666

On to step 2:
When dividing 19 by 666, we get 0 with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 666

Step 3:
666 can be fit into 195 0 times, resulting in a remainder of 195.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 195 and we're left with 195.
Take the next digit (4) from the dividend and append it to 195, then repeat: 1954 / 666

Advancing to step 4:
When dividing 1954 by 666, we get 2 with a remainder of 622.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 622 after subtracting 1332 from 1954.
Grab the next digit (0) from the dividend, add it to 622, then carry on: 6220 / 666

Going ahead to step 5:
6220 divided by 666 is 9 with a remainder of 226.
Write down 9 as next digit of the result. 
Result so far: 29.0
If we take 5994 away from 6220, we end up with 226.
Bring next digit (1) of the dividend behind the 226 and repeat the process: 2261 / 666

Going ahead to step 6:
When dividing 2261 by 666, we get 3 with a remainder of 263.
Record the quotient 3 as the next digit in the result. 
Result so far: 293.0
Subtracting 1998 from 2261 leaves us with 263.
Bring next digit (9) of the dividend behind the 263 and repeat the process: 2639 / 666

On to step 7:
2639 divided by 666 is 3 with a remainder of 641.
The next digit of our result is 3. 
Result so far: 2933.0
Deduct 1998 from 2639 and we're left with 641.
Include the next digit (6) from the dividend after 641, then repeat: 6416 / 666

Going ahead to step 8:
The number 666 fits into 6416 9 times, leaving a remainder of 422.
The next digit of our result is 9. 
Result so far: 29339.0
Subtracting 5994 from 6416 leaves us with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Step 9:
When dividing 4220 by 666, we get 6 with a remainder of 224.
Record the quotient 6 as the next digit in the result. 
Result so far: 29339.6
Deduct 3996 from 4220 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 10:
The number 666 fits into 2240 3 times, leaving a remainder of 242.
Record the quotient 3 as the next digit in the result. 
Result so far: 29339.63
Subtracting 1998 from 2240 leaves us with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

On to step 11:
666 goes into 2420 3 times with a remainder of 422.
Write down 3 as next digit of the result. 
Result so far: 29339.633
Subtracting 1998 from 2420 leaves us with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

In conclusion, the division gives 29339.633 with a balance of 0.0422.
