56728978 ÷ 87 
Let's see how many times 87 fits into 56728978.

Going ahead to step 1:
87 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 87

Let's proceed to step 2:
56 divided by 87 is 0 with a remainder of 56.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 56 and we're left with 56.
Append the next digit (7) from the dividend to 56 and continue with: 567 / 87

Going ahead to step 3:
567 divided by 87 is 6 with a remainder of 45.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 522 from 567, we get 45.
Fetch the next digit (2) from the dividend, attach it to 45 and continue: 452 / 87

Going ahead to step 4:
87 can be fit into 452 5 times, resulting in a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 65.0
Deduct 435 from 452 and we're left with 17.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 87

Going ahead to step 5:
87 goes into 178 2 times with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 652.0
Deduct 174 from 178 and we're left with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 87

On to step 6:
If we divide 49 by 87, we get 0 and a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 6520.0
The remainder is 49 after subtracting 0 from 49.
Include the next digit (7) from the dividend after 49, then repeat: 497 / 87

Going ahead to step 7:
497 divided by 87 is 5 with a remainder of 62.
The next digit of our result is 5. 
Result so far: 65205.0
The remainder is 62 after subtracting 435 from 497.
Append the next digit (8) from the dividend to 62 and continue with: 628 / 87

On to step 8:
The number 87 fits into 628 7 times, leaving a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 652057.0
The remainder is 19 after subtracting 609 from 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 9:
87 goes into 190 2 times with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 652057.2
Deduct 174 from 190 and we're left 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 10:
When dividing 160 by 87, we get 1 with a remainder of 73.
Use 1 as the next digit of our solution. 
Result so far: 652057.21
Subtracting 87 from 160 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 11:
87 can be fit into 730 8 times, resulting in a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 652057.218
If we subtract 696 from 730, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 12:
87 goes into 340 3 times with a remainder of 79.
Put 3 as the next digit of the answer. 
Result so far: 652057.2183
If we take 261 away from 340, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 13:
790 divided by 87 is 9 with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 652057.21839
Deduct 783 from 790 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 14:
87 can be fit into 70 0 times, resulting in a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 652057.21839
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 15:
When dividing 700 by 87, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 652057.2183908
If we subtract 696 from 700, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 16:
When dividing 40 by 87, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 652057.2183908
Deduct 0 from 40 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.

The final outcome is 652057.2183908, with a leftover of 4e-08.
