We divide 1684749 by 871
The aim is to understand the frequency of 871 in 1684749.

Let's proceed to step 1:
871 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 871

Going ahead to step 2:
871 can be fit into 16 0 times, resulting in a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 871

On to step 3:
168 divided by 871 is 0 with a remainder of 168.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 168, we end up with 168.
Fetch the next digit (4) from the dividend, attach it to 168 and continue: 1684 / 871

On to step 4:
If we divide 1684 by 871, we get 1 and a remainder of 813.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 813 after subtracting 871 from 1684.
Take the next digit (7) from the dividend and append it to 813, then repeat: 8137 / 871

On to step 5:
If we divide 8137 by 871, we get 9 and a remainder of 298.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Deduct 7839 from 8137 and we're left with 298.
Bring next digit (4) of the dividend behind the 298 and repeat the process: 2984 / 871

Moving on to step 6:
The number 871 fits into 2984 3 times, leaving a remainder of 371.
The number 3 becomes the next digit in our result. 
Result so far: 193.0
If we take 2613 away from 2984, we end up with 371.
Fetch the next digit (9) from the dividend, attach it to 371 and continue: 3719 / 871

Moving on to step 7:
871 can be fit into 3719 4 times, resulting in a remainder of 235.
Use 4 as the next digit of our solution. 
Result so far: 1934.0
The remainder is 235 after subtracting 3484 from 3719.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Advancing to step 8:
871 can be fit into 2350 2 times, resulting in a remainder of 608.
Use 2 as the next digit of our solution. 
Result so far: 1934.2
Deduct 1742 from 2350 and we're left with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Step 9:
871 can be fit into 6080 6 times, resulting in a remainder of 854.
The next digit of our result is 6. 
Result so far: 1934.26
Deduct 5226 from 6080 and we're left with 854.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8540, and continue the process.

Let's proceed to step 10:
If we divide 8540 by 871, we get 9 and a remainder of 701.
Use 9 as the next digit of our solution. 
Result so far: 1934.269
Subtracting 7839 from 8540 leaves us with 701.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7010, and continue the process.

Let's proceed to step 11:
871 can be fit into 7010 8 times, resulting in a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 1934.2698
If we subtract 6968 from 7010, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 12:
871 goes into 420 0 times with a remainder of 420.
Record the quotient 0 as the next digit in the result. 
Result so far: 1934.2698
Subtracting 0 from 420 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 13:
When dividing 4200 by 871, we get 4 with a remainder of 716.
Write down 4 as next digit of the result. 
Result so far: 1934.269804
If we take 3484 away from 4200, we end up with 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

Moving on to step 14:
7160 divided by 871 is 8 with a remainder of 192.
Put 8 as the next digit of the answer. 
Result so far: 1934.2698048
Subtract 6968 from 7160 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 15:
The number 871 fits into 1920 2 times, leaving a remainder of 178.
The number 2 becomes the next digit in our result. 
Result so far: 1934.26980482
If we subtract 1742 from 1920, we get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

The final outcome is 1934.26980482, with a leftover of 1.78e-07.
