We're dividing 55648586 by 81 
We're looking to find how many times 81 goes into 55648586.

Moving on to step 1:
81 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 81

Let's proceed to step 2:
If we divide 55 by 81, we get 0 and a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Grab the next digit (6) from the dividend, add it to 55, then carry on: 556 / 81

On to step 3:
81 can be fit into 556 6 times, resulting in a remainder of 70.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 486 from 556 to get 70.
Grab the next digit (4) from the dividend, add it to 70, then carry on: 704 / 81

Let's proceed to step 4:
When dividing 704 by 81, we get 8 with a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 68.0
Subtracting 648 from 704 leaves us with 56.
Take the next digit (8) from the dividend and append it to 56, then repeat: 568 / 81

Advancing to step 5:
81 goes into 568 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 687.0
Subtracting 567 from 568 leaves us with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 81

Let's proceed to step 6:
81 can be fit into 15 0 times, resulting in a remainder of 15.
The next digit of our result is 0. 
Result so far: 6870.0
If we take 0 away from 15, we end up with 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 81

Step 7:
81 goes into 158 1 times with a remainder of 77.
Put 1 as the next digit of the answer. 
Result so far: 68701.0
If we subtract 81 from 158, we get 77.
Take the next digit (6) from the dividend and append it to 77, then repeat: 776 / 81

On to step 8:
If we divide 776 by 81, we get 9 and a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 687019.0
Deduct 729 from 776 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 9:
The number 81 fits into 470 5 times, leaving a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 687019.5
If we take 405 away from 470, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 10:
650 divided by 81 is 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 687019.58
The remainder is 2 after subtracting 648 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 11:
81 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 687019.58
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
The number 81 fits into 200 2 times, leaving a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 687019.5802
Subtracting 162 from 200 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 13:
If we divide 380 by 81, we get 4 and a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 687019.58024
Deduct 324 from 380 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 14:
If we divide 560 by 81, we get 6 and a remainder of 74.
Write down 6 as next digit of the result. 
Result so far: 687019.580246
The remainder is 74 after subtracting 486 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 15:
740 divided by 81 is 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 687019.5802469
Deduct 729 from 740 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 16:
110 divided by 81 is 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 687019.58024691
If we subtract 81 from 110, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final outcome is 687019.58024691, with a leftover of 2.9e-08.
