We look at the division of 78665266 by 198 
We're looking to find how many times 198 goes into 78665266.

Going ahead to step 1:
If we divide 7 by 198, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 198

Moving on to step 2:
The number 198 fits into 78 0 times, leaving a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Fetch the next digit (6) from the dividend, attach it to 78 and continue: 786 / 198

Going ahead to step 3:
786 divided by 198 is 3 with a remainder of 192.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 594 from 786 leaves us with 192.
Include the next digit (6) from the dividend after 192, then repeat: 1926 / 198

On to step 4:
If we divide 1926 by 198, we get 9 and a remainder of 144.
Write down 9 as next digit of the result. 
Result so far: 39.0
If we take 1782 away from 1926, we end up with 144.
Grab the next digit (5) from the dividend, add it to 144, then carry on: 1445 / 198

Moving on to step 5:
When dividing 1445 by 198, we get 7 with a remainder of 59.
Write down 7 as next digit of the result. 
Result so far: 397.0
If we subtract 1386 from 1445, we get 59.
Fetch the next digit (2) from the dividend, attach it to 59 and continue: 592 / 198

Advancing to step 6:
The number 198 fits into 592 2 times, leaving a remainder of 196.
Use 2 as the next digit of our solution. 
Result so far: 3972.0
Deduct 396 from 592 and we're left with 196.
Grab the next digit (6) from the dividend, add it to 196, then carry on: 1966 / 198

Moving on to step 7:
198 goes into 1966 9 times with a remainder of 184.
Use 9 as the next digit of our solution. 
Result so far: 39729.0
Deduct 1782 from 1966 and we're left with 184.
Append the next digit (6) from the dividend to 184 and continue with: 1846 / 198

Going ahead to step 8:
1846 divided by 198 is 9 with a remainder of 64.
Use 9 as the next digit of our solution. 
Result so far: 397299.0
If we take 1782 away from 1846, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 9:
198 goes into 640 3 times with a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 397299.3
If we subtract 594 from 640, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 10:
If we divide 460 by 198, we get 2 and a remainder of 64.
The next digit of our result is 2. 
Result so far: 397299.32
If we take 396 away from 460, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 11:
198 can be fit into 640 3 times, resulting in a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 397299.323
The remainder is 46 after subtracting 594 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 12:
460 divided by 198 is 2 with a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 397299.3232
Subtract 396 from 460 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 13:
When dividing 640 by 198, we get 3 with a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 397299.32323
The remainder is 46 after subtracting 594 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 14:
198 can be fit into 460 2 times, resulting in a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 397299.323232
Deduct 396 from 460 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 15:
198 can be fit into 640 3 times, resulting in a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 397299.3232323
If we take 594 away from 640, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 16:
When dividing 460 by 198, we get 2 with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 397299.32323232
Subtracting 396 from 460 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 397299.32323232 with a remainder of 6.4e-08.
