Let's divide 86840453 by 746
The aim is to understand the frequency of 746 in 86840453.

On to step 1:
746 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 746

Going ahead to step 2:
If we divide 86 by 746, we get 0 and a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Append the next digit (8) from the dividend to 86 and continue with: 868 / 746

Moving on to step 3:
If we divide 868 by 746, we get 1 and a remainder of 122.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 746 from 868 and we're left with 122.
Grab the next digit (4) from the dividend, add it to 122, then carry on: 1224 / 746

Going ahead to step 4:
746 can be fit into 1224 1 times, resulting in a remainder of 478.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 478 after subtracting 746 from 1224.
Bring next digit (0) of the dividend behind the 478 and repeat the process: 4780 / 746

Step 5:
746 goes into 4780 6 times with a remainder of 304.
Record the quotient 6 as the next digit in the result. 
Result so far: 116.0
Subtracting 4476 from 4780 leaves us with 304.
Fetch the next digit (4) from the dividend, attach it to 304 and continue: 3044 / 746

Going ahead to step 6:
746 can be fit into 3044 4 times, resulting in a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 1164.0
If we subtract 2984 from 3044, we get 60.
Append the next digit (5) from the dividend to 60 and continue with: 605 / 746

Step 7:
746 can be fit into 605 0 times, resulting in a remainder of 605.
The next digit of our result is 0. 
Result so far: 11640.0
Deduct 0 from 605 and we're left with 605.
Grab the next digit (3) from the dividend, add it to 605, then carry on: 6053 / 746

Moving on to step 8:
746 can be fit into 6053 8 times, resulting in a remainder of 85.
Record the quotient 8 as the next digit in the result. 
Result so far: 116408.0
Subtract 5968 from 6053 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 9:
746 can be fit into 850 1 times, resulting in a remainder of 104.
Put 1 as the next digit of the answer. 
Result so far: 116408.1
If we take 746 away from 850, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 10:
746 goes into 1040 1 times with a remainder of 294.
The number 1 becomes the next digit in our result. 
Result so far: 116408.11
The remainder is 294 after subtracting 746 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

The final outcome is 116408.11, with a leftover of 0.294.
