887683 divided by 31 
The aim is to understand the frequency of 31 in 887683.

Advancing to step 1:
When dividing 8 by 31, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 31

Moving on to step 2:
If we divide 88 by 31, we get 2 and a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 62 from 88 to get 26.
Include the next digit (7) from the dividend after 26, then repeat: 267 / 31

Advancing to step 3:
31 can be fit into 267 8 times, resulting in a remainder of 19.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtract 248 from 267 to get 19.
Grab the next digit (6) from the dividend, add it to 19, then carry on: 196 / 31

On to step 4:
196 divided by 31 is 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 286.0
If we take 186 away from 196, we end up with 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 31

Advancing to step 5:
31 goes into 108 3 times with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 2863.0
Deduct 93 from 108 and we're left with 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 31

Going ahead to step 6:
The number 31 fits into 153 4 times, leaving a remainder of 29.
Use 4 as the next digit of our solution. 
Result so far: 28634.0
If we take 124 away from 153, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
The number 31 fits into 290 9 times, leaving a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 28634.9
Subtract 279 from 290 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 8:
110 divided by 31 is 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 28634.93
If we subtract 93 from 110, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 9:
170 divided by 31 is 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 28634.935
If we take 155 away from 170, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
31 goes into 150 4 times with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 28634.9354
Deduct 124 from 150 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 11:
260 divided by 31 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 28634.93548
Deduct 248 from 260 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
31 can be fit into 120 3 times, resulting in a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 28634.935483
If we subtract 93 from 120, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 13:
31 goes into 270 8 times with a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 28634.9354838
If we subtract 248 from 270, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 14:
31 goes into 220 7 times with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 28634.93548387
If we subtract 217 from 220, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

In conclusion, the division gives 28634.93548387 with a balance of 3e-09.
