78243866 ÷ 56 
Our goal is to divide 78243866 by 56.

Let's proceed to step 1:
When dividing 7 by 56, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 56

Advancing to step 2:
56 can be fit into 78 1 times, resulting in a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 56 away from 78, we end up with 22.
Take the next digit (2) from the dividend and append it to 22, then repeat: 222 / 56

Advancing to step 3:
56 can be fit into 222 3 times, resulting in a remainder of 54.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 168 away from 222, we end up with 54.
Include the next digit (4) from the dividend after 54, then repeat: 544 / 56

Step 4:
56 goes into 544 9 times with a remainder of 40.
The number 9 becomes the next digit in our result. 
Result so far: 139.0
If we subtract 504 from 544, we get 40.
Fetch the next digit (3) from the dividend, attach it to 40 and continue: 403 / 56

Step 5:
The number 56 fits into 403 7 times, leaving a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 1397.0
Subtract 392 from 403 to get 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 56

Step 6:
If we divide 118 by 56, we get 2 and a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 13972.0
If we take 112 away from 118, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 56

Going ahead to step 7:
When dividing 66 by 56, we get 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 139721.0
Subtracting 56 from 66 leaves us with 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 56

On to step 8:
56 can be fit into 106 1 times, resulting in a remainder of 50.
Record the quotient 1 as the next digit in the result. 
Result so far: 1397211.0
If we take 56 away from 106, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
If we divide 500 by 56, we get 8 and a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 1397211.8
Deduct 448 from 500 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 10:
The number 56 fits into 520 9 times, leaving a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 1397211.89
Subtract 504 from 520 to get 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 56 fits into 160 2 times, leaving a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 1397211.892
The remainder is 48 after subtracting 112 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 12:
If we divide 480 by 56, we get 8 and a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 1397211.8928
Subtract 448 from 480 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 13:
56 goes into 320 5 times with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 1397211.89285
Deduct 280 from 320 and we're left 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 14:
When dividing 400 by 56, we get 7 with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 1397211.892857
If we subtract 392 from 400, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 15:
80 divided by 56 is 1 with a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 1397211.8928571
Subtracting 56 from 80 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 16:
56 goes into 240 4 times with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 1397211.89285714
The remainder is 16 after subtracting 224 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 1397211.89285714 with a balance of 1.6e-08.
