We're dividing 20571866 by 551 
Let's see how many times 551 fits into 20571866.

Going ahead to step 1:
551 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 551

Moving on to step 2:
When dividing 20 by 551, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Fetch the next digit (5) from the dividend, attach it to 20 and continue: 205 / 551

Let's proceed to step 3:
205 divided by 551 is 0 with a remainder of 205.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 205 leaves us with 205.
Fetch the next digit (7) from the dividend, attach it to 205 and continue: 2057 / 551

Step 4:
If we divide 2057 by 551, we get 3 and a remainder of 404.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 1653 from 2057 to get 404.
Bring next digit (1) of the dividend behind the 404 and repeat the process: 4041 / 551

On to step 5:
551 can be fit into 4041 7 times, resulting in a remainder of 184.
The next digit of our result is 7. 
Result so far: 37.0
If we take 3857 away from 4041, we end up with 184.
Fetch the next digit (8) from the dividend, attach it to 184 and continue: 1848 / 551

Let's proceed to step 6:
551 goes into 1848 3 times with a remainder of 195.
Put 3 as the next digit of the answer. 
Result so far: 373.0
If we subtract 1653 from 1848, we get 195.
Fetch the next digit (6) from the dividend, attach it to 195 and continue: 1956 / 551

Moving on to step 7:
1956 divided by 551 is 3 with a remainder of 303.
The number 3 becomes the next digit in our result. 
Result so far: 3733.0
Deduct 1653 from 1956 and we're left with 303.
Grab the next digit (6) from the dividend, add it to 303, then carry on: 3036 / 551

Let's proceed to step 8:
If we divide 3036 by 551, we get 5 and a remainder of 281.
Put 5 as the next digit of the answer. 
Result so far: 37335.0
Subtract 2755 from 3036 to get 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Moving on to step 9:
When dividing 2810 by 551, we get 5 with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 37335.5
If we subtract 2755 from 2810, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 10:
551 goes into 550 0 times with a remainder of 550.
The number 0 becomes the next digit in our result. 
Result so far: 37335.5
If we take 0 away from 550, we end up with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Advancing to step 11:
5500 divided by 551 is 9 with a remainder of 541.
Use 9 as the next digit of our solution. 
Result so far: 37335.509
If we take 4959 away from 5500, we end up with 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Step 12:
The number 551 fits into 5410 9 times, leaving a remainder of 451.
Write down 9 as next digit of the result. 
Result so far: 37335.5099
If we subtract 4959 from 5410, we get 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

The quotient of the division is 37335.5099, and the remainder is 0.00451.
