We divide 71308410 by 891
The aim is to understand the frequency of 891 in 71308410.

Step 1:
7 divided by 891 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 891

Going ahead to step 2:
71 divided by 891 is 0 with a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Take the next digit (3) from the dividend and append it to 71, then repeat: 713 / 891

Moving on to step 3:
891 can be fit into 713 0 times, resulting in a remainder of 713.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 713 and we're left with 713.
Grab the next digit (0) from the dividend, add it to 713, then carry on: 7130 / 891

Going ahead to step 4:
891 can be fit into 7130 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 7128 away from 7130, we end up with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 891

On to step 5:
The number 891 fits into 28 0 times, leaving a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 80.0
If we subtract 0 from 28, we get 28.
Grab the next digit (4) from the dividend, add it to 28, then carry on: 284 / 891

Going ahead to step 6:
The number 891 fits into 284 0 times, leaving a remainder of 284.
The next digit of our result is 0. 
Result so far: 800.0
Subtracting 0 from 284 leaves us with 284.
Bring next digit (1) of the dividend behind the 284 and repeat the process: 2841 / 891

Going ahead to step 7:
When dividing 2841 by 891, we get 3 with a remainder of 168.
Use 3 as the next digit of our solution. 
Result so far: 8003.0
Subtracting 2673 from 2841 leaves us with 168.
Append the next digit (0) from the dividend to 168 and continue with: 1680 / 891

On to step 8:
If we divide 1680 by 891, we get 1 and a remainder of 789.
Record the quotient 1 as the next digit in the result. 
Result so far: 80031.0
If we subtract 891 from 1680, we get 789.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7890, and continue the process.

Advancing to step 9:
If we divide 7890 by 891, we get 8 and a remainder of 762.
The next digit of our result is 8. 
Result so far: 80031.8
Subtracting 7128 from 7890 leaves us with 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

Advancing to step 10:
891 can be fit into 7620 8 times, resulting in a remainder of 492.
The number 8 becomes the next digit in our result. 
Result so far: 80031.88
The remainder is 492 after subtracting 7128 from 7620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

The final outcome is 80031.88, with a leftover of 0.492.
