We look at the division of 82187158 by 891 
The aim is to understand the frequency of 891 in 82187158.

On to step 1:
891 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 891

Step 2:
The number 891 fits into 82 0 times, leaving a remainder of 82.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 82 to get 82.
Grab the next digit (1) from the dividend, add it to 82, then carry on: 821 / 891

Moving on to step 3:
When dividing 821 by 891, we get 0 with a remainder of 821.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 821 and we're left with 821.
Fetch the next digit (8) from the dividend, attach it to 821 and continue: 8218 / 891

Step 4:
The number 891 fits into 8218 9 times, leaving a remainder of 199.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 8019 from 8218, we get 199.
Fetch the next digit (7) from the dividend, attach it to 199 and continue: 1997 / 891

Step 5:
The number 891 fits into 1997 2 times, leaving a remainder of 215.
Use 2 as the next digit of our solution. 
Result so far: 92.0
If we subtract 1782 from 1997, we get 215.
Include the next digit (1) from the dividend after 215, then repeat: 2151 / 891

Going ahead to step 6:
If we divide 2151 by 891, we get 2 and a remainder of 369.
Write down 2 as next digit of the result. 
Result so far: 922.0
Deduct 1782 from 2151 and we're left with 369.
Append the next digit (5) from the dividend to 369 and continue with: 3695 / 891

Step 7:
The number 891 fits into 3695 4 times, leaving a remainder of 131.
The next digit of our result is 4. 
Result so far: 9224.0
Subtract 3564 from 3695 to get 131.
Append the next digit (8) from the dividend to 131 and continue with: 1318 / 891

Advancing to step 8:
If we divide 1318 by 891, we get 1 and a remainder of 427.
The number 1 becomes the next digit in our result. 
Result so far: 92241.0
If we subtract 891 from 1318, we get 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

Let's proceed to step 9:
The number 891 fits into 4270 4 times, leaving a remainder of 706.
Put 4 as the next digit of the answer. 
Result so far: 92241.4
Subtracting 3564 from 4270 leaves us with 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

On to step 10:
891 can be fit into 7060 7 times, resulting in a remainder of 823.
Record the quotient 7 as the next digit in the result. 
Result so far: 92241.47
If we take 6237 away from 7060, we end up with 823.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8230, and continue the process.

On to step 11:
When dividing 8230 by 891, we get 9 with a remainder of 211.
Use 9 as the next digit of our solution. 
Result so far: 92241.479
If we subtract 8019 from 8230, we get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Let's proceed to step 12:
891 goes into 2110 2 times with a remainder of 328.
Record the quotient 2 as the next digit in the result. 
Result so far: 92241.4792
Deduct 1782 from 2110 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 13:
If we divide 3280 by 891, we get 3 and a remainder of 607.
The number 3 becomes the next digit in our result. 
Result so far: 92241.47923
Deduct 2673 from 3280 and we're left with 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Step 14:
The number 891 fits into 6070 6 times, leaving a remainder of 724.
Use 6 as the next digit of our solution. 
Result so far: 92241.479236
Subtract 5346 from 6070 to get 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

On to step 15:
When dividing 7240 by 891, we get 8 with a remainder of 112.
Use 8 as the next digit of our solution. 
Result so far: 92241.4792368
If we take 7128 away from 7240, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 16:
When dividing 1120 by 891, we get 1 with a remainder of 229.
The number 1 becomes the next digit in our result. 
Result so far: 92241.47923681
The remainder is 229 after subtracting 891 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

The quotient of the division is 92241.47923681, and the remainder is 2.29e-07.
