86539714 ÷ 837 
The aim is to understand the frequency of 837 in 86539714.

Advancing to step 1:
The number 837 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 837

On to step 2:
86 divided by 837 is 0 with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Take the next digit (5) from the dividend and append it to 86, then repeat: 865 / 837

Advancing to step 3:
837 goes into 865 1 times with a remainder of 28.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 837 from 865 and we're left with 28.
Append the next digit (3) from the dividend to 28 and continue with: 283 / 837

Advancing to step 4:
837 can be fit into 283 0 times, resulting in a remainder of 283.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 283 and we're left with 283.
Append the next digit (9) from the dividend to 283 and continue with: 2839 / 837

On to step 5:
837 goes into 2839 3 times with a remainder of 328.
Use 3 as the next digit of our solution. 
Result so far: 103.0
Subtract 2511 from 2839 to get 328.
Take the next digit (7) from the dividend and append it to 328, then repeat: 3287 / 837

Let's proceed to step 6:
3287 divided by 837 is 3 with a remainder of 776.
Record the quotient 3 as the next digit in the result. 
Result so far: 1033.0
The remainder is 776 after subtracting 2511 from 3287.
Include the next digit (1) from the dividend after 776, then repeat: 7761 / 837

Going ahead to step 7:
837 goes into 7761 9 times with a remainder of 228.
Write down 9 as next digit of the result. 
Result so far: 10339.0
The remainder is 228 after subtracting 7533 from 7761.
Fetch the next digit (4) from the dividend, attach it to 228 and continue: 2284 / 837

Going ahead to step 8:
If we divide 2284 by 837, we get 2 and a remainder of 610.
Use 2 as the next digit of our solution. 
Result so far: 103392.0
If we subtract 1674 from 2284, we get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

On to step 9:
If we divide 6100 by 837, we get 7 and a remainder of 241.
Write down 7 as next digit of the result. 
Result so far: 103392.7
Subtracting 5859 from 6100 leaves us with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Moving on to step 10:
If we divide 2410 by 837, we get 2 and a remainder of 736.
The number 2 becomes the next digit in our result. 
Result so far: 103392.72
If we take 1674 away from 2410, we end up with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Advancing to step 11:
The number 837 fits into 7360 8 times, leaving a remainder of 664.
The next digit of our result is 8. 
Result so far: 103392.728
The remainder is 664 after subtracting 6696 from 7360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Let's proceed to step 12:
When dividing 6640 by 837, we get 7 with a remainder of 781.
Record the quotient 7 as the next digit in the result. 
Result so far: 103392.7287
Deduct 5859 from 6640 and we're left with 781.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7810, and continue the process.

Let's proceed to step 13:
7810 divided by 837 is 9 with a remainder of 277.
Put 9 as the next digit of the answer. 
Result so far: 103392.72879
Subtract 7533 from 7810 to get 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Step 14:
When dividing 2770 by 837, we get 3 with a remainder of 259.
Put 3 as the next digit of the answer. 
Result so far: 103392.728793
Deduct 2511 from 2770 and we're left with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Step 15:
When dividing 2590 by 837, we get 3 with a remainder of 79.
Write down 3 as next digit of the result. 
Result so far: 103392.7287933
The remainder is 79 after subtracting 2511 from 2590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

In conclusion, the division gives 103392.7287933 with a balance of 7.9e-07.
