We divide 21478147 by 801
The aim is to understand the frequency of 801 in 21478147.

Step 1:
When dividing 2 by 801, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 801

Let's proceed to step 2:
The number 801 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 801

Advancing to step 3:
801 goes into 214 0 times with a remainder of 214.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 214, we end up with 214.
Fetch the next digit (7) from the dividend, attach it to 214 and continue: 2147 / 801

Moving on to step 4:
When dividing 2147 by 801, we get 2 with a remainder of 545.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 1602 from 2147 leaves us with 545.
Fetch the next digit (8) from the dividend, attach it to 545 and continue: 5458 / 801

Advancing to step 5:
801 can be fit into 5458 6 times, resulting in a remainder of 652.
The next digit of our result is 6. 
Result so far: 26.0
If we subtract 4806 from 5458, we get 652.
Append the next digit (1) from the dividend to 652 and continue with: 6521 / 801

Advancing to step 6:
When dividing 6521 by 801, we get 8 with a remainder of 113.
The number 8 becomes the next digit in our result. 
Result so far: 268.0
Subtracting 6408 from 6521 leaves us with 113.
Fetch the next digit (4) from the dividend, attach it to 113 and continue: 1134 / 801

Step 7:
801 can be fit into 1134 1 times, resulting in a remainder of 333.
Put 1 as the next digit of the answer. 
Result so far: 2681.0
Subtracting 801 from 1134 leaves us with 333.
Fetch the next digit (7) from the dividend, attach it to 333 and continue: 3337 / 801

On to step 8:
When dividing 3337 by 801, we get 4 with a remainder of 133.
The number 4 becomes the next digit in our result. 
Result so far: 26814.0
Subtract 3204 from 3337 to get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Advancing to step 9:
When dividing 1330 by 801, we get 1 with a remainder of 529.
Put 1 as the next digit of the answer. 
Result so far: 26814.1
If we take 801 away from 1330, we end up with 529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

Going ahead to step 10:
If we divide 5290 by 801, we get 6 and a remainder of 484.
Record the quotient 6 as the next digit in the result. 
Result so far: 26814.16
Subtracting 4806 from 5290 leaves us with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Going ahead to step 11:
801 can be fit into 4840 6 times, resulting in a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 26814.166
The remainder is 34 after subtracting 4806 from 4840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final result is 26814.166 with a remainder of 0.0034.
