1679231 ÷ 869 
The aim is to understand the frequency of 869 in 1679231.

On to step 1:
869 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 869

Step 2:
869 can be fit into 16 0 times, resulting in a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Include the next digit (7) from the dividend after 16, then repeat: 167 / 869

On to step 3:
The number 869 fits into 167 0 times, leaving a remainder of 167.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 167, we get 167.
Append the next digit (9) from the dividend to 167 and continue with: 1679 / 869

Step 4:
869 goes into 1679 1 times with a remainder of 810.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 869 from 1679 leaves us with 810.
Append the next digit (2) from the dividend to 810 and continue with: 8102 / 869

Moving on to step 5:
8102 divided by 869 is 9 with a remainder of 281.
The next digit of our result is 9. 
Result so far: 19.0
Deduct 7821 from 8102 and we're left with 281.
Fetch the next digit (3) from the dividend, attach it to 281 and continue: 2813 / 869

Advancing to step 6:
2813 divided by 869 is 3 with a remainder of 206.
Use 3 as the next digit of our solution. 
Result so far: 193.0
Deduct 2607 from 2813 and we're left with 206.
Grab the next digit (1) from the dividend, add it to 206, then carry on: 2061 / 869

Moving on to step 7:
869 can be fit into 2061 2 times, resulting in a remainder of 323.
Put 2 as the next digit of the answer. 
Result so far: 1932.0
Deduct 1738 from 2061 and we're left with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Advancing to step 8:
869 goes into 3230 3 times with a remainder of 623.
Record the quotient 3 as the next digit in the result. 
Result so far: 1932.3
If we take 2607 away from 3230, we end up with 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Moving on to step 9:
When dividing 6230 by 869, we get 7 with a remainder of 147.
Use 7 as the next digit of our solution. 
Result so far: 1932.37
The remainder is 147 after subtracting 6083 from 6230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Going ahead to step 10:
869 can be fit into 1470 1 times, resulting in a remainder of 601.
Use 1 as the next digit of our solution. 
Result so far: 1932.371
Deduct 869 from 1470 and we're left with 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Advancing to step 11:
When dividing 6010 by 869, we get 6 with a remainder of 796.
Record the quotient 6 as the next digit in the result. 
Result so far: 1932.3716
The remainder is 796 after subtracting 5214 from 6010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

On to step 12:
If we divide 7960 by 869, we get 9 and a remainder of 139.
Write down 9 as next digit of the result. 
Result so far: 1932.37169
If we subtract 7821 from 7960, we get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Step 13:
The number 869 fits into 1390 1 times, leaving a remainder of 521.
The next digit of our result is 1. 
Result so far: 1932.371691
Subtracting 869 from 1390 leaves us with 521.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5210, and continue the process.

Moving on to step 14:
869 can be fit into 5210 5 times, resulting in a remainder of 865.
Use 5 as the next digit of our solution. 
Result so far: 1932.3716915
If we subtract 4345 from 5210, we get 865.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8650, and continue the process.

On to step 15:
869 can be fit into 8650 9 times, resulting in a remainder of 829.
Put 9 as the next digit of the answer. 
Result so far: 1932.37169159
If we take 7821 away from 8650, we end up with 829.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8290, and continue the process.

In conclusion, the division gives 1932.37169159 with a balance of 8.29e-07.
