We're dividing 55221560 by 605 
We want to divide 55221560 by 605.

Going ahead to step 1:
5 divided by 605 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 605

Step 2:
When dividing 55 by 605, we get 0 with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Fetch the next digit (2) from the dividend, attach it to 55 and continue: 552 / 605

Moving on to step 3:
552 divided by 605 is 0 with a remainder of 552.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 552 and we're left with 552.
Grab the next digit (2) from the dividend, add it to 552, then carry on: 5522 / 605

Moving on to step 4:
If we divide 5522 by 605, we get 9 and a remainder of 77.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 5445 from 5522 and we're left with 77.
Grab the next digit (1) from the dividend, add it to 77, then carry on: 771 / 605

On to step 5:
The number 605 fits into 771 1 times, leaving a remainder of 166.
Put 1 as the next digit of the answer. 
Result so far: 91.0
If we subtract 605 from 771, we get 166.
Bring next digit (5) of the dividend behind the 166 and repeat the process: 1665 / 605

On to step 6:
605 can be fit into 1665 2 times, resulting in a remainder of 455.
Use 2 as the next digit of our solution. 
Result so far: 912.0
Subtract 1210 from 1665 to get 455.
Grab the next digit (6) from the dividend, add it to 455, then carry on: 4556 / 605

Going ahead to step 7:
If we divide 4556 by 605, we get 7 and a remainder of 321.
Write down 7 as next digit of the result. 
Result so far: 9127.0
If we subtract 4235 from 4556, we get 321.
Take the next digit (0) from the dividend and append it to 321, then repeat: 3210 / 605

Moving on to step 8:
605 goes into 3210 5 times with a remainder of 185.
Record the quotient 5 as the next digit in the result. 
Result so far: 91275.0
Subtract 3025 from 3210 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 9:
If we divide 1850 by 605, we get 3 and a remainder of 35.
Record the quotient 3 as the next digit in the result. 
Result so far: 91275.3
The remainder is 35 after subtracting 1815 from 1850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 10:
350 divided by 605 is 0 with a remainder of 350.
Put 0 as the next digit of the answer. 
Result so far: 91275.3
The remainder is 350 after subtracting 0 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 11:
The number 605 fits into 3500 5 times, leaving a remainder of 475.
Use 5 as the next digit of our solution. 
Result so far: 91275.305
Subtract 3025 from 3500 to get 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

On to step 12:
If we divide 4750 by 605, we get 7 and a remainder of 515.
The next digit of our result is 7. 
Result so far: 91275.3057
Subtract 4235 from 4750 to get 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Step 13:
605 can be fit into 5150 8 times, resulting in a remainder of 310.
Put 8 as the next digit of the answer. 
Result so far: 91275.30578
Subtract 4840 from 5150 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 14:
The number 605 fits into 3100 5 times, leaving a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 91275.305785
The remainder is 75 after subtracting 3025 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 15:
If we divide 750 by 605, we get 1 and a remainder of 145.
The next digit of our result is 1. 
Result so far: 91275.3057851
Subtracting 605 from 750 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 16:
If we divide 1450 by 605, we get 2 and a remainder of 240.
Put 2 as the next digit of the answer. 
Result so far: 91275.30578512
Subtract 1210 from 1450 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final result is 91275.30578512 with a remainder of 2.4e-07.
