Let's divide 84264541 by 801
The aim is to understand the frequency of 801 in 84264541.

Step 1:
8 divided by 801 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 801

Moving on to step 2:
If we divide 84 by 801, we get 0 and a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Append the next digit (2) from the dividend to 84 and continue with: 842 / 801

Going ahead to step 3:
842 divided by 801 is 1 with a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 801 from 842 to get 41.
Grab the next digit (6) from the dividend, add it to 41, then carry on: 416 / 801

Moving on to step 4:
If we divide 416 by 801, we get 0 and a remainder of 416.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 416 to get 416.
Grab the next digit (4) from the dividend, add it to 416, then carry on: 4164 / 801

Going ahead to step 5:
If we divide 4164 by 801, we get 5 and a remainder of 159.
Record the quotient 5 as the next digit in the result. 
Result so far: 105.0
Subtract 4005 from 4164 to get 159.
Grab the next digit (5) from the dividend, add it to 159, then carry on: 1595 / 801

On to step 6:
The number 801 fits into 1595 1 times, leaving a remainder of 794.
Write down 1 as next digit of the result. 
Result so far: 1051.0
Subtract 801 from 1595 to get 794.
Take the next digit (4) from the dividend and append it to 794, then repeat: 7944 / 801

Advancing to step 7:
801 goes into 7944 9 times with a remainder of 735.
Write down 9 as next digit of the result. 
Result so far: 10519.0
Deduct 7209 from 7944 and we're left with 735.
Take the next digit (1) from the dividend and append it to 735, then repeat: 7351 / 801

Step 8:
The number 801 fits into 7351 9 times, leaving a remainder of 142.
Put 9 as the next digit of the answer. 
Result so far: 105199.0
If we take 7209 away from 7351, we end up with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

On to step 9:
The number 801 fits into 1420 1 times, leaving a remainder of 619.
The next digit of our result is 1. 
Result so far: 105199.1
Subtract 801 from 1420 to get 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

On to step 10:
The number 801 fits into 6190 7 times, leaving a remainder of 583.
Write down 7 as next digit of the result. 
Result so far: 105199.17
Subtract 5607 from 6190 to get 583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

On to step 11:
When dividing 5830 by 801, we get 7 with a remainder of 223.
The next digit of our result is 7. 
Result so far: 105199.177
Subtract 5607 from 5830 to get 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

The final outcome is 105199.177, with a leftover of 0.0223.
