197224 ÷ 78 
We want to divide 197224 by 78.

Going ahead to step 1:
When dividing 1 by 78, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 78

On to step 2:
If we divide 19 by 78, we get 0 and 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 (7) from the dividend to 19 and continue with: 197 / 78

Step 3:
When dividing 197 by 78, we get 2 with a remainder of 41.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 156 from 197 to get 41.
Grab the next digit (2) from the dividend, add it to 41, then carry on: 412 / 78

Going ahead to step 4:
412 divided by 78 is 5 with a remainder of 22.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Deduct 390 from 412 and we're left with 22.
Fetch the next digit (2) from the dividend, attach it to 22 and continue: 222 / 78

Moving on to step 5:
When dividing 222 by 78, we get 2 with a remainder of 66.
The number 2 becomes the next digit in our result. 
Result so far: 252.0
Subtract 156 from 222 to get 66.
Bring next digit (4) of the dividend behind the 66 and repeat the process: 664 / 78

Let's proceed to step 6:
664 divided by 78 is 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 2528.0
If we take 624 away from 664, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 7:
When dividing 400 by 78, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 2528.5
Subtract 390 from 400 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
78 goes into 100 1 times with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 2528.51
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
78 goes into 220 2 times with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 2528.512
Subtract 156 from 220 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.

Step 10:
78 can be fit into 640 8 times, resulting in a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 2528.5128
Subtracting 624 from 640 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
The number 78 fits into 160 2 times, leaving a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 2528.51282
Subtracting 156 from 160 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
78 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 2528.51282
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
78 can be fit into 400 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 2528.5128205
Subtract 390 from 400 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
78 can be fit into 100 1 times, resulting in a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 2528.51282051
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 2528.51282051, with a leftover of 2.2e-08.
