83574276 ÷ 820 
The aim is to understand the frequency of 820 in 83574276.

Let's proceed to step 1:
If we divide 8 by 820, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 820

Moving on to step 2:
820 can be fit into 83 0 times, resulting in a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Include the next digit (5) from the dividend after 83, then repeat: 835 / 820

Going ahead to step 3:
When dividing 835 by 820, we get 1 with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 15 after subtracting 820 from 835.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 820

On to step 4:
The number 820 fits into 157 0 times, leaving a remainder of 157.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 157, we get 157.
Include the next digit (4) from the dividend after 157, then repeat: 1574 / 820

On to step 5:
820 can be fit into 1574 1 times, resulting in a remainder of 754.
The next digit of our result is 1. 
Result so far: 101.0
If we subtract 820 from 1574, we get 754.
Take the next digit (2) from the dividend and append it to 754, then repeat: 7542 / 820

Going ahead to step 6:
820 can be fit into 7542 9 times, resulting in a remainder of 162.
Put 9 as the next digit of the answer. 
Result so far: 1019.0
The remainder is 162 after subtracting 7380 from 7542.
Take the next digit (7) from the dividend and append it to 162, then repeat: 1627 / 820

Let's proceed to step 7:
When dividing 1627 by 820, we get 1 with a remainder of 807.
Use 1 as the next digit of our solution. 
Result so far: 10191.0
If we take 820 away from 1627, we end up with 807.
Bring next digit (6) of the dividend behind the 807 and repeat the process: 8076 / 820

On to step 8:
The number 820 fits into 8076 9 times, leaving a remainder of 696.
The next digit of our result is 9. 
Result so far: 101919.0
Subtracting 7380 from 8076 leaves us with 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

On to step 9:
When dividing 6960 by 820, we get 8 with a remainder of 400.
Record the quotient 8 as the next digit in the result. 
Result so far: 101919.8
If we take 6560 away from 6960, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 10:
The number 820 fits into 4000 4 times, leaving a remainder of 720.
Record the quotient 4 as the next digit in the result. 
Result so far: 101919.84
Subtract 3280 from 4000 to get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Let's proceed to step 11:
If we divide 7200 by 820, we get 8 and a remainder of 640.
Put 8 as the next digit of the answer. 
Result so far: 101919.848
If we subtract 6560 from 7200, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 12:
820 can be fit into 6400 7 times, resulting in a remainder of 660.
Use 7 as the next digit of our solution. 
Result so far: 101919.8487
Deduct 5740 from 6400 and we're left with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Advancing to step 13:
If we divide 6600 by 820, we get 8 and a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 101919.84878
Deduct 6560 from 6600 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 14:
If we divide 400 by 820, we get 0 and a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 101919.84878
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 15:
820 goes into 4000 4 times with a remainder of 720.
Use 4 as the next digit of our solution. 
Result so far: 101919.8487804
Deduct 3280 from 4000 and we're left with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

On to step 16:
7200 divided by 820 is 8 with a remainder of 640.
The number 8 becomes the next digit in our result. 
Result so far: 101919.84878048
Subtracting 6560 from 7200 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

The final result is 101919.84878048 with a remainder of 6.4e-07.
