35716398 divided by 820 
The aim is to understand the frequency of 820 in 35716398.

Step 1:
If we divide 3 by 820, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 820

Advancing to step 2:
The number 820 fits into 35 0 times, leaving a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Grab the next digit (7) from the dividend, add it to 35, then carry on: 357 / 820

Let's proceed to step 3:
820 goes into 357 0 times with a remainder of 357.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 357 leaves us with 357.
Take the next digit (1) from the dividend and append it to 357, then repeat: 3571 / 820

Step 4:
If we divide 3571 by 820, we get 4 and a remainder of 291.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 3280 from 3571, we get 291.
Take the next digit (6) from the dividend and append it to 291, then repeat: 2916 / 820

Step 5:
820 goes into 2916 3 times with a remainder of 456.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Subtracting 2460 from 2916 leaves us with 456.
Take the next digit (3) from the dividend and append it to 456, then repeat: 4563 / 820

Let's proceed to step 6:
820 can be fit into 4563 5 times, resulting in a remainder of 463.
Put 5 as the next digit of the answer. 
Result so far: 435.0
Deduct 4100 from 4563 and we're left with 463.
Grab the next digit (9) from the dividend, add it to 463, then carry on: 4639 / 820

Moving on to step 7:
4639 divided by 820 is 5 with a remainder of 539.
The number 5 becomes the next digit in our result. 
Result so far: 4355.0
If we take 4100 away from 4639, we end up with 539.
Append the next digit (8) from the dividend to 539 and continue with: 5398 / 820

Step 8:
The number 820 fits into 5398 6 times, leaving a remainder of 478.
Put 6 as the next digit of the answer. 
Result so far: 43556.0
Subtract 4920 from 5398 to get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

On to step 9:
820 goes into 4780 5 times with a remainder of 680.
The number 5 becomes the next digit in our result. 
Result so far: 43556.5
Subtracting 4100 from 4780 leaves us with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Advancing to step 10:
6800 divided by 820 is 8 with a remainder of 240.
The number 8 becomes the next digit in our result. 
Result so far: 43556.58
Deduct 6560 from 6800 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 11:
820 can be fit into 2400 2 times, resulting in a remainder of 760.
Put 2 as the next digit of the answer. 
Result so far: 43556.582
If we subtract 1640 from 2400, we get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Going ahead to step 12:
820 goes into 7600 9 times with a remainder of 220.
The number 9 becomes the next digit in our result. 
Result so far: 43556.5829
If we take 7380 away from 7600, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 13:
820 can be fit into 2200 2 times, resulting in a remainder of 560.
Use 2 as the next digit of our solution. 
Result so far: 43556.58292
If we subtract 1640 from 2200, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 14:
If we divide 5600 by 820, we get 6 and a remainder of 680.
The number 6 becomes the next digit in our result. 
Result so far: 43556.582926
If we subtract 4920 from 5600, we get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Going ahead to step 15:
6800 divided by 820 is 8 with a remainder of 240.
The next digit of our result is 8. 
Result so far: 43556.5829268
Subtracting 6560 from 6800 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 16:
2400 divided by 820 is 2 with a remainder of 760.
Record the quotient 2 as the next digit in the result. 
Result so far: 43556.58292682
Subtracting 1640 from 2400 leaves us with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

The final outcome is 43556.58292682, with a leftover of 7.6e-07.
