We look at the division of 86916263 by 844 
The aim is to understand the frequency of 844 in 86916263.

On to step 1:
The number 844 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 844

On to step 2:
844 goes into 86 0 times with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Fetch the next digit (9) from the dividend, attach it to 86 and continue: 869 / 844

Let's proceed to step 3:
844 goes into 869 1 times with a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 25 after subtracting 844 from 869.
Take the next digit (1) from the dividend and append it to 25, then repeat: 251 / 844

Going ahead to step 4:
When dividing 251 by 844, we get 0 with a remainder of 251.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 251 leaves us with 251.
Include the next digit (6) from the dividend after 251, then repeat: 2516 / 844

Advancing to step 5:
844 goes into 2516 2 times with a remainder of 828.
Put 2 as the next digit of the answer. 
Result so far: 102.0
Deduct 1688 from 2516 and we're left with 828.
Fetch the next digit (2) from the dividend, attach it to 828 and continue: 8282 / 844

Advancing to step 6:
844 goes into 8282 9 times with a remainder of 686.
The next digit of our result is 9. 
Result so far: 1029.0
If we subtract 7596 from 8282, we get 686.
Grab the next digit (6) from the dividend, add it to 686, then carry on: 6866 / 844

Moving on to step 7:
The number 844 fits into 6866 8 times, leaving a remainder of 114.
Write down 8 as next digit of the result. 
Result so far: 10298.0
The remainder is 114 after subtracting 6752 from 6866.
Fetch the next digit (3) from the dividend, attach it to 114 and continue: 1143 / 844

Advancing to step 8:
The number 844 fits into 1143 1 times, leaving a remainder of 299.
Use 1 as the next digit of our solution. 
Result so far: 102981.0
Deduct 844 from 1143 and we're left with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Advancing to step 9:
2990 divided by 844 is 3 with a remainder of 458.
Record the quotient 3 as the next digit in the result. 
Result so far: 102981.3
If we take 2532 away from 2990, we end up with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

On to step 10:
844 goes into 4580 5 times with a remainder of 360.
Use 5 as the next digit of our solution. 
Result so far: 102981.35
Deduct 4220 from 4580 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 11:
3600 divided by 844 is 4 with a remainder of 224.
Put 4 as the next digit of the answer. 
Result so far: 102981.354
Deduct 3376 from 3600 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 12:
The number 844 fits into 2240 2 times, leaving a remainder of 552.
The number 2 becomes the next digit in our result. 
Result so far: 102981.3542
Deduct 1688 from 2240 and we're left with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Let's proceed to step 13:
If we divide 5520 by 844, we get 6 and a remainder of 456.
The next digit of our result is 6. 
Result so far: 102981.35426
Deduct 5064 from 5520 and we're left with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Advancing to step 14:
844 can be fit into 4560 5 times, resulting in a remainder of 340.
The next digit of our result is 5. 
Result so far: 102981.354265
If we take 4220 away from 4560, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 15:
When dividing 3400 by 844, we get 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 102981.3542654
If we take 3376 away from 3400, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 16:
844 goes into 240 0 times with a remainder of 240.
Put 0 as the next digit of the answer. 
Result so far: 102981.3542654
Subtracting 0 from 240 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.

The quotient of the division is 102981.3542654, and the remainder is 2.4e-07.
