We look at the division of 39493158 by 801 
The aim is to understand the frequency of 801 in 39493158.

Let's proceed to step 1:
3 divided by 801 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 801

Moving on to step 2:
39 divided by 801 is 0 with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Fetch the next digit (4) from the dividend, attach it to 39 and continue: 394 / 801

Step 3:
394 divided by 801 is 0 with a remainder of 394.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 394 to get 394.
Bring next digit (9) of the dividend behind the 394 and repeat the process: 3949 / 801

Step 4:
If we divide 3949 by 801, we get 4 and a remainder of 745.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 3204 from 3949 leaves us with 745.
Append the next digit (3) from the dividend to 745 and continue with: 7453 / 801

Moving on to step 5:
If we divide 7453 by 801, we get 9 and a remainder of 244.
Use 9 as the next digit of our solution. 
Result so far: 49.0
If we subtract 7209 from 7453, we get 244.
Include the next digit (1) from the dividend after 244, then repeat: 2441 / 801

Moving on to step 6:
If we divide 2441 by 801, we get 3 and a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 493.0
If we take 2403 away from 2441, we end up with 38.
Fetch the next digit (5) from the dividend, attach it to 38 and continue: 385 / 801

Going ahead to step 7:
If we divide 385 by 801, we get 0 and a remainder of 385.
Use 0 as the next digit of our solution. 
Result so far: 4930.0
If we subtract 0 from 385, we get 385.
Append the next digit (8) from the dividend to 385 and continue with: 3858 / 801

Let's proceed to step 8:
If we divide 3858 by 801, we get 4 and a remainder of 654.
The next digit of our result is 4. 
Result so far: 49304.0
Subtracting 3204 from 3858 leaves us with 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Going ahead to step 9:
The number 801 fits into 6540 8 times, leaving a remainder of 132.
The number 8 becomes the next digit in our result. 
Result so far: 49304.8
If we subtract 6408 from 6540, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 10:
The number 801 fits into 1320 1 times, leaving a remainder of 519.
Record the quotient 1 as the next digit in the result. 
Result so far: 49304.81
Subtract 801 from 1320 to get 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Let's proceed to step 11:
The number 801 fits into 5190 6 times, leaving a remainder of 384.
Write down 6 as next digit of the result. 
Result so far: 49304.816
Subtracting 4806 from 5190 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 12:
801 goes into 3840 4 times with a remainder of 636.
Record the quotient 4 as the next digit in the result. 
Result so far: 49304.8164
If we subtract 3204 from 3840, we get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Let's proceed to step 13:
The number 801 fits into 6360 7 times, leaving a remainder of 753.
The next digit of our result is 7. 
Result so far: 49304.81647
Subtract 5607 from 6360 to get 753.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7530, and continue the process.

Advancing to step 14:
The number 801 fits into 7530 9 times, leaving a remainder of 321.
Use 9 as the next digit of our solution. 
Result so far: 49304.816479
The remainder is 321 after subtracting 7209 from 7530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Moving on to step 15:
3210 divided by 801 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 49304.8164794
If we take 3204 away from 3210, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 16:
60 divided by 801 is 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 49304.8164794
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 49304.8164794, with a leftover of 6e-08.
