We look at the division of 19665966 by 828 
We want to figure out the number of times 19665966 can be divided by 828.

Let's proceed to step 1:
When dividing 1 by 828, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 828

Moving on to step 2:
828 can be fit into 19 0 times, resulting in a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Append the next digit (6) from the dividend to 19 and continue with: 196 / 828

Step 3:
196 divided by 828 is 0 with a remainder of 196.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 196 to get 196.
Append the next digit (6) from the dividend to 196 and continue with: 1966 / 828

Going ahead to step 4:
828 goes into 1966 2 times with a remainder of 310.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 1656 away from 1966, we end up with 310.
Bring next digit (5) of the dividend behind the 310 and repeat the process: 3105 / 828

On to step 5:
828 goes into 3105 3 times with a remainder of 621.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtracting 2484 from 3105 leaves us with 621.
Append the next digit (9) from the dividend to 621 and continue with: 6219 / 828

Let's proceed to step 6:
828 can be fit into 6219 7 times, resulting in a remainder of 423.
Record the quotient 7 as the next digit in the result. 
Result so far: 237.0
If we subtract 5796 from 6219, we get 423.
Take the next digit (6) from the dividend and append it to 423, then repeat: 4236 / 828

Advancing to step 7:
When dividing 4236 by 828, we get 5 with a remainder of 96.
Use 5 as the next digit of our solution. 
Result so far: 2375.0
If we take 4140 away from 4236, we end up with 96.
Bring next digit (6) of the dividend behind the 96 and repeat the process: 966 / 828

Step 8:
When dividing 966 by 828, we get 1 with a remainder of 138.
Write down 1 as next digit of the result. 
Result so far: 23751.0
Subtract 828 from 966 to get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Moving on to step 9:
828 goes into 1380 1 times with a remainder of 552.
The number 1 becomes the next digit in our result. 
Result so far: 23751.1
If we subtract 828 from 1380, we 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.

Advancing to step 10:
When dividing 5520 by 828, we get 6 with a remainder of 552.
Write down 6 as next digit of the result. 
Result so far: 23751.16
If we subtract 4968 from 5520, we 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.

Let's proceed to step 11:
828 goes into 5520 6 times with a remainder of 552.
Put 6 as the next digit of the answer. 
Result so far: 23751.166
If we subtract 4968 from 5520, we 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.

Our division results in 23751.166 with a remaining 0.0552.
