We look at the division of 45678810 by 396 
We want to figure out the number of times 45678810 can be divided by 396.

Step 1:
If we divide 4 by 396, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 396

On to step 2:
The number 396 fits into 45 0 times, leaving a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Take the next digit (6) from the dividend and append it to 45, then repeat: 456 / 396

Advancing to step 3:
If we divide 456 by 396, we get 1 and a remainder of 60.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 396 from 456 to get 60.
Grab the next digit (7) from the dividend, add it to 60, then carry on: 607 / 396

Advancing to step 4:
396 can be fit into 607 1 times, resulting in a remainder of 211.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 396 from 607 to get 211.
Append the next digit (8) from the dividend to 211 and continue with: 2118 / 396

Step 5:
If we divide 2118 by 396, we get 5 and a remainder of 138.
Write down 5 as next digit of the result. 
Result so far: 115.0
Deduct 1980 from 2118 and we're left with 138.
Bring next digit (8) of the dividend behind the 138 and repeat the process: 1388 / 396

Advancing to step 6:
When dividing 1388 by 396, we get 3 with a remainder of 200.
Use 3 as the next digit of our solution. 
Result so far: 1153.0
Subtract 1188 from 1388 to get 200.
Append the next digit (1) from the dividend to 200 and continue with: 2001 / 396

Let's proceed to step 7:
396 can be fit into 2001 5 times, resulting in a remainder of 21.
Record the quotient 5 as the next digit in the result. 
Result so far: 11535.0
The remainder is 21 after subtracting 1980 from 2001.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 396

Let's proceed to step 8:
396 goes into 210 0 times with a remainder of 210.
Record the quotient 0 as the next digit in the result. 
Result so far: 115350.0
If we take 0 away from 210, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 9:
396 goes into 2100 5 times with a remainder of 120.
The next digit of our result is 5. 
Result so far: 115350.5
If we subtract 1980 from 2100, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 10:
If we divide 1200 by 396, we get 3 and a remainder of 12.
The next digit of our result is 3. 
Result so far: 115350.53
If we subtract 1188 from 1200, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 11:
120 divided by 396 is 0 with a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 115350.53
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 12:
If we divide 1200 by 396, we get 3 and a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 115350.5303
The remainder is 12 after subtracting 1188 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
When dividing 120 by 396, we get 0 with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 115350.5303
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 14:
If we divide 1200 by 396, we get 3 and a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 115350.530303
Deduct 1188 from 1200 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 15:
120 divided by 396 is 0 with a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 115350.530303
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 16:
1200 divided by 396 is 3 with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 115350.53030303
Deduct 1188 from 1200 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 115350.53030303, with a leftover of 1.2e-08.
