84837721 divided by 811 
The aim is to understand the frequency of 811 in 84837721.

On to step 1:
811 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 811

Step 2:
If we divide 84 by 811, we get 0 and a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 84, we end up with 84.
Include the next digit (8) from the dividend after 84, then repeat: 848 / 811

On to step 3:
When dividing 848 by 811, we get 1 with a remainder of 37.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 811 from 848, we get 37.
Grab the next digit (3) from the dividend, add it to 37, then carry on: 373 / 811

Moving on to step 4:
811 goes into 373 0 times with a remainder of 373.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 373 after subtracting 0 from 373.
Bring next digit (7) of the dividend behind the 373 and repeat the process: 3737 / 811

Going ahead to step 5:
The number 811 fits into 3737 4 times, leaving a remainder of 493.
Put 4 as the next digit of the answer. 
Result so far: 104.0
Subtract 3244 from 3737 to get 493.
Bring next digit (7) of the dividend behind the 493 and repeat the process: 4937 / 811

On to step 6:
4937 divided by 811 is 6 with a remainder of 71.
Put 6 as the next digit of the answer. 
Result so far: 1046.0
The remainder is 71 after subtracting 4866 from 4937.
Include the next digit (2) from the dividend after 71, then repeat: 712 / 811

On to step 7:
712 divided by 811 is 0 with a remainder of 712.
The number 0 becomes the next digit in our result. 
Result so far: 10460.0
The remainder is 712 after subtracting 0 from 712.
Grab the next digit (1) from the dividend, add it to 712, then carry on: 7121 / 811

Step 8:
7121 divided by 811 is 8 with a remainder of 633.
Write down 8 as next digit of the result. 
Result so far: 104608.0
Subtract 6488 from 7121 to get 633.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6330, and continue the process.

Going ahead to step 9:
The number 811 fits into 6330 7 times, leaving a remainder of 653.
Record the quotient 7 as the next digit in the result. 
Result so far: 104608.7
If we subtract 5677 from 6330, we get 653.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6530, and continue the process.

Let's proceed to step 10:
811 goes into 6530 8 times with a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 104608.78
Subtracting 6488 from 6530 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 11:
If we divide 420 by 811, we get 0 and a remainder of 420.
Record the quotient 0 as the next digit in the result. 
Result so far: 104608.78
Deduct 0 from 420 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 12:
When dividing 4200 by 811, we get 5 with a remainder of 145.
The next digit of our result is 5. 
Result so far: 104608.7805
If we subtract 4055 from 4200, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Moving on to step 13:
The number 811 fits into 1450 1 times, leaving a remainder of 639.
Use 1 as the next digit of our solution. 
Result so far: 104608.78051
Deduct 811 from 1450 and we're left with 639.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6390, and continue the process.

Moving on to step 14:
When dividing 6390 by 811, we get 7 with a remainder of 713.
The number 7 becomes the next digit in our result. 
Result so far: 104608.780517
The remainder is 713 after subtracting 5677 from 6390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7130, and continue the process.

Going ahead to step 15:
The number 811 fits into 7130 8 times, leaving a remainder of 642.
Write down 8 as next digit of the result. 
Result so far: 104608.7805178
Subtracting 6488 from 7130 leaves us with 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

Step 16:
6420 divided by 811 is 7 with a remainder of 743.
Put 7 as the next digit of the answer. 
Result so far: 104608.78051787
If we take 5677 away from 6420, we end up with 743.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7430, and continue the process.

The final result is 104608.78051787 with a remainder of 7.43e-07.
