20003310 ÷ 551 
The aim is to understand the frequency of 551 in 20003310.

On to step 1:
If we divide 2 by 551, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 551

Advancing to step 2:
551 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Take the next digit (0) from the dividend and append it to 20, then repeat: 200 / 551

Advancing to step 3:
The number 551 fits into 200 0 times, leaving a remainder of 200.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 200 after subtracting 0 from 200.
Fetch the next digit (0) from the dividend, attach it to 200 and continue: 2000 / 551

Going ahead to step 4:
If we divide 2000 by 551, we get 3 and a remainder of 347.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 347 after subtracting 1653 from 2000.
Append the next digit (3) from the dividend to 347 and continue with: 3473 / 551

Moving on to step 5:
The number 551 fits into 3473 6 times, leaving a remainder of 167.
Put 6 as the next digit of the answer. 
Result so far: 36.0
Subtract 3306 from 3473 to get 167.
Include the next digit (3) from the dividend after 167, then repeat: 1673 / 551

Going ahead to step 6:
When dividing 1673 by 551, we get 3 with a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 363.0
If we subtract 1653 from 1673, we get 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 551

Moving on to step 7:
When dividing 201 by 551, we get 0 with a remainder of 201.
Write down 0 as next digit of the result. 
Result so far: 3630.0
Subtract 0 from 201 to get 201.
Fetch the next digit (0) from the dividend, attach it to 201 and continue: 2010 / 551

Let's proceed to step 8:
551 goes into 2010 3 times with a remainder of 357.
Write down 3 as next digit of the result. 
Result so far: 36303.0
Subtracting 1653 from 2010 leaves us with 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Step 9:
The number 551 fits into 3570 6 times, leaving a remainder of 264.
Put 6 as the next digit of the answer. 
Result so far: 36303.6
Deduct 3306 from 3570 and we're left with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Advancing to step 10:
551 goes into 2640 4 times with a remainder of 436.
The next digit of our result is 4. 
Result so far: 36303.64
If we take 2204 away from 2640, we end up with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Step 11:
If we divide 4360 by 551, we get 7 and a remainder of 503.
Write down 7 as next digit of the result. 
Result so far: 36303.647
Subtracting 3857 from 4360 leaves us with 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Step 12:
If we divide 5030 by 551, we get 9 and a remainder of 71.
Put 9 as the next digit of the answer. 
Result so far: 36303.6479
If we subtract 4959 from 5030, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 13:
If we divide 710 by 551, we get 1 and a remainder of 159.
Put 1 as the next digit of the answer. 
Result so far: 36303.64791
If we take 551 away from 710, we end up with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Let's proceed to step 14:
551 can be fit into 1590 2 times, resulting in a remainder of 488.
Write down 2 as next digit of the result. 
Result so far: 36303.647912
Deduct 1102 from 1590 and we're left with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Going ahead to step 15:
If we divide 4880 by 551, we get 8 and a remainder of 472.
The next digit of our result is 8. 
Result so far: 36303.6479128
If we subtract 4408 from 4880, we get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

On to step 16:
551 can be fit into 4720 8 times, resulting in a remainder of 312.
Put 8 as the next digit of the answer. 
Result so far: 36303.64791288
Subtracting 4408 from 4720 leaves us with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

The final outcome is 36303.64791288, with a leftover of 3.12e-07.
