91793635 ÷ 820 
The aim is to understand the frequency of 820 in 91793635.

Advancing to step 1:
The number 820 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 820

Let's proceed to step 2:
91 divided by 820 is 0 with a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Take the next digit (7) from the dividend and append it to 91, then repeat: 917 / 820

Moving on to step 3:
When dividing 917 by 820, we get 1 with a remainder of 97.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 820 from 917 leaves us with 97.
Bring next digit (9) of the dividend behind the 97 and repeat the process: 979 / 820

Going ahead to step 4:
When dividing 979 by 820, we get 1 with a remainder of 159.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 820 away from 979, we end up with 159.
Include the next digit (3) from the dividend after 159, then repeat: 1593 / 820

Step 5:
1593 divided by 820 is 1 with a remainder of 773.
Put 1 as the next digit of the answer. 
Result so far: 111.0
Subtracting 820 from 1593 leaves us with 773.
Bring next digit (6) of the dividend behind the 773 and repeat the process: 7736 / 820

Advancing to step 6:
The number 820 fits into 7736 9 times, leaving a remainder of 356.
Use 9 as the next digit of our solution. 
Result so far: 1119.0
Subtract 7380 from 7736 to get 356.
Bring next digit (3) of the dividend behind the 356 and repeat the process: 3563 / 820

Moving on to step 7:
When dividing 3563 by 820, we get 4 with a remainder of 283.
The number 4 becomes the next digit in our result. 
Result so far: 11194.0
Subtract 3280 from 3563 to get 283.
Fetch the next digit (5) from the dividend, attach it to 283 and continue: 2835 / 820

Moving on to step 8:
The number 820 fits into 2835 3 times, leaving a remainder of 375.
Put 3 as the next digit of the answer. 
Result so far: 111943.0
Subtract 2460 from 2835 to get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Advancing to step 9:
When dividing 3750 by 820, we get 4 with a remainder of 470.
Use 4 as the next digit of our solution. 
Result so far: 111943.4
Subtracting 3280 from 3750 leaves us with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Step 10:
If we divide 4700 by 820, we get 5 and a remainder of 600.
Record the quotient 5 as the next digit in the result. 
Result so far: 111943.45
If we subtract 4100 from 4700, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 11:
If we divide 6000 by 820, we get 7 and a remainder of 260.
Record the quotient 7 as the next digit in the result. 
Result so far: 111943.457
If we take 5740 away from 6000, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 12:
When dividing 2600 by 820, we get 3 with a remainder of 140.
Use 3 as the next digit of our solution. 
Result so far: 111943.4573
Deduct 2460 from 2600 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 13:
When dividing 1400 by 820, we get 1 with a remainder of 580.
Record the quotient 1 as the next digit in the result. 
Result so far: 111943.45731
Subtracting 820 from 1400 leaves us with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Moving on to step 14:
When dividing 5800 by 820, we get 7 with a remainder of 60.
The number 7 becomes the next digit in our result. 
Result so far: 111943.457317
Subtract 5740 from 5800 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 15:
If we divide 600 by 820, we get 0 and a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 111943.457317
Deduct 0 from 600 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 16:
If we divide 6000 by 820, we get 7 and a remainder of 260.
The next digit of our result is 7. 
Result so far: 111943.45731707
Subtract 5740 from 6000 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

In conclusion, the division gives 111943.45731707 with a balance of 2.6e-07.
