We divide 21675749 by 801
The aim is to understand the frequency of 801 in 21675749.

Step 1:
801 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 801

Moving on to step 2:
If we divide 21 by 801, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 801

Moving on to step 3:
801 can be fit into 216 0 times, resulting in a remainder of 216.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 216 leaves us with 216.
Bring next digit (7) of the dividend behind the 216 and repeat the process: 2167 / 801

Step 4:
801 goes into 2167 2 times with a remainder of 565.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 565 after subtracting 1602 from 2167.
Take the next digit (5) from the dividend and append it to 565, then repeat: 5655 / 801

Going ahead to step 5:
If we divide 5655 by 801, we get 7 and a remainder of 48.
Write down 7 as next digit of the result. 
Result so far: 27.0
Subtracting 5607 from 5655 leaves us with 48.
Bring next digit (7) of the dividend behind the 48 and repeat the process: 487 / 801

Moving on to step 6:
801 can be fit into 487 0 times, resulting in a remainder of 487.
Write down 0 as next digit of the result. 
Result so far: 270.0
If we take 0 away from 487, we end up with 487.
Append the next digit (4) from the dividend to 487 and continue with: 4874 / 801

Advancing to step 7:
When dividing 4874 by 801, we get 6 with a remainder of 68.
Record the quotient 6 as the next digit in the result. 
Result so far: 2706.0
Subtract 4806 from 4874 to get 68.
Bring next digit (9) of the dividend behind the 68 and repeat the process: 689 / 801

Let's proceed to step 8:
689 divided by 801 is 0 with a remainder of 689.
Record the quotient 0 as the next digit in the result. 
Result so far: 27060.0
The remainder is 689 after subtracting 0 from 689.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6890, and continue the process.

Step 9:
801 goes into 6890 8 times with a remainder of 482.
The next digit of our result is 8. 
Result so far: 27060.8
The remainder is 482 after subtracting 6408 from 6890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Step 10:
801 can be fit into 4820 6 times, resulting in a remainder of 14.
The next digit of our result is 6. 
Result so far: 27060.86
The remainder is 14 after subtracting 4806 from 4820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
801 can be fit into 140 0 times, resulting in a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 27060.86
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 12:
If we divide 1400 by 801, we get 1 and a remainder of 599.
Write down 1 as next digit of the result. 
Result so far: 27060.8601
Deduct 801 from 1400 and we're left with 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Step 13:
The number 801 fits into 5990 7 times, leaving a remainder of 383.
Write down 7 as next digit of the result. 
Result so far: 27060.86017
If we take 5607 away from 5990, we end up with 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Advancing to step 14:
If we divide 3830 by 801, we get 4 and a remainder of 626.
Put 4 as the next digit of the answer. 
Result so far: 27060.860174
Deduct 3204 from 3830 and we're left with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

On to step 15:
When dividing 6260 by 801, we get 7 with a remainder of 653.
Put 7 as the next digit of the answer. 
Result so far: 27060.8601747
The remainder is 653 after subtracting 5607 from 6260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6530, and continue the process.

Advancing to step 16:
If we divide 6530 by 801, we get 8 and a remainder of 122.
Record the quotient 8 as the next digit in the result. 
Result so far: 27060.86017478
The remainder is 122 after subtracting 6408 from 6530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

The final result is 27060.86017478 with a remainder of 1.22e-07.
