We look at the division of 59789036 by 801 
The aim is to understand the frequency of 801 in 59789036.

On to step 1:
If we divide 5 by 801, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 801

On to step 2:
The number 801 fits into 59 0 times, leaving a remainder of 59.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 59, we end up with 59.
Fetch the next digit (7) from the dividend, attach it to 59 and continue: 597 / 801

Step 3:
801 can be fit into 597 0 times, resulting in a remainder of 597.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 597 to get 597.
Fetch the next digit (8) from the dividend, attach it to 597 and continue: 5978 / 801

Advancing to step 4:
When dividing 5978 by 801, we get 7 with a remainder of 371.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 5607 from 5978, we get 371.
Include the next digit (9) from the dividend after 371, then repeat: 3719 / 801

On to step 5:
When dividing 3719 by 801, we get 4 with a remainder of 515.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
The remainder is 515 after subtracting 3204 from 3719.
Fetch the next digit (0) from the dividend, attach it to 515 and continue: 5150 / 801

Moving on to step 6:
The number 801 fits into 5150 6 times, leaving a remainder of 344.
The next digit of our result is 6. 
Result so far: 746.0
The remainder is 344 after subtracting 4806 from 5150.
Take the next digit (3) from the dividend and append it to 344, then repeat: 3443 / 801

Going ahead to step 7:
801 can be fit into 3443 4 times, resulting in a remainder of 239.
The number 4 becomes the next digit in our result. 
Result so far: 7464.0
Subtract 3204 from 3443 to get 239.
Append the next digit (6) from the dividend to 239 and continue with: 2396 / 801

Step 8:
If we divide 2396 by 801, we get 2 and a remainder of 794.
The next digit of our result is 2. 
Result so far: 74642.0
Subtract 1602 from 2396 to get 794.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

Advancing to step 9:
7940 divided by 801 is 9 with a remainder of 731.
Record the quotient 9 as the next digit in the result. 
Result so far: 74642.9
Deduct 7209 from 7940 and we're left with 731.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7310, and continue the process.

Step 10:
If we divide 7310 by 801, we get 9 and a remainder of 101.
The number 9 becomes the next digit in our result. 
Result so far: 74642.99
Subtract 7209 from 7310 to get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

After the division, we end up with 74642.99 and a remainder of 0.101.
