Let's divide 58377113 by 821
The aim is to understand the frequency of 821 in 58377113.

Going ahead to step 1:
When dividing 5 by 821, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 821

Moving on to step 2:
821 goes into 58 0 times with a remainder of 58.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 58 and we're left with 58.
Bring next digit (3) of the dividend behind the 58 and repeat the process: 583 / 821

Going ahead to step 3:
The number 821 fits into 583 0 times, leaving a remainder of 583.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 583 after subtracting 0 from 583.
Grab the next digit (7) from the dividend, add it to 583, then carry on: 5837 / 821

On to step 4:
When dividing 5837 by 821, we get 7 with a remainder of 90.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 5747 from 5837 to get 90.
Bring next digit (7) of the dividend behind the 90 and repeat the process: 907 / 821

Step 5:
907 divided by 821 is 1 with a remainder of 86.
Write down 1 as next digit of the result. 
Result so far: 71.0
Subtracting 821 from 907 leaves us with 86.
Append the next digit (1) from the dividend to 86 and continue with: 861 / 821

Advancing to step 6:
821 goes into 861 1 times with a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 711.0
Subtracting 821 from 861 leaves us with 40.
Fetch the next digit (1) from the dividend, attach it to 40 and continue: 401 / 821

On to step 7:
If we divide 401 by 821, we get 0 and a remainder of 401.
Put 0 as the next digit of the answer. 
Result so far: 7110.0
If we subtract 0 from 401, we get 401.
Include the next digit (3) from the dividend after 401, then repeat: 4013 / 821

Moving on to step 8:
If we divide 4013 by 821, we get 4 and a remainder of 729.
Use 4 as the next digit of our solution. 
Result so far: 71104.0
Subtract 3284 from 4013 to get 729.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7290, and continue the process.

Step 9:
If we divide 7290 by 821, we get 8 and a remainder of 722.
The next digit of our result is 8. 
Result so far: 71104.8
Subtracting 6568 from 7290 leaves us with 722.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7220, and continue the process.

Going ahead to step 10:
If we divide 7220 by 821, we get 8 and a remainder of 652.
Use 8 as the next digit of our solution. 
Result so far: 71104.88
Deduct 6568 from 7220 and we're left with 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

The final result is 71104.88 with a remainder of 0.652.
