We're dividing 1874099 by 870 
The aim is to understand the frequency of 870 in 1874099.

Moving on to step 1:
When dividing 1 by 870, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 870

Going ahead to step 2:
When dividing 18 by 870, we get 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 870

Step 3:
The number 870 fits into 187 0 times, leaving a remainder of 187.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 187 after subtracting 0 from 187.
Include the next digit (4) from the dividend after 187, then repeat: 1874 / 870

Advancing to step 4:
870 can be fit into 1874 2 times, resulting in a remainder of 134.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 1740 from 1874 and we're left with 134.
Take the next digit (0) from the dividend and append it to 134, then repeat: 1340 / 870

On to step 5:
870 goes into 1340 1 times with a remainder of 470.
The next digit of our result is 1. 
Result so far: 21.0
The remainder is 470 after subtracting 870 from 1340.
Fetch the next digit (9) from the dividend, attach it to 470 and continue: 4709 / 870

On to step 6:
870 can be fit into 4709 5 times, resulting in a remainder of 359.
Record the quotient 5 as the next digit in the result. 
Result so far: 215.0
The remainder is 359 after subtracting 4350 from 4709.
Append the next digit (9) from the dividend to 359 and continue with: 3599 / 870

Advancing to step 7:
When dividing 3599 by 870, we get 4 with a remainder of 119.
Use 4 as the next digit of our solution. 
Result so far: 2154.0
Subtracting 3480 from 3599 leaves us with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Moving on to step 8:
The number 870 fits into 1190 1 times, leaving a remainder of 320.
The number 1 becomes the next digit in our result. 
Result so far: 2154.1
The remainder is 320 after subtracting 870 from 1190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 9:
870 goes into 3200 3 times with a remainder of 590.
The number 3 becomes the next digit in our result. 
Result so far: 2154.13
Deduct 2610 from 3200 and we're left with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Going ahead to step 10:
870 goes into 5900 6 times with a remainder of 680.
Put 6 as the next digit of the answer. 
Result so far: 2154.136
If we subtract 5220 from 5900, we get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Step 11:
When dividing 6800 by 870, we get 7 with a remainder of 710.
Put 7 as the next digit of the answer. 
Result so far: 2154.1367
The remainder is 710 after subtracting 6090 from 6800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Advancing to step 12:
870 can be fit into 7100 8 times, resulting in a remainder of 140.
Record the quotient 8 as the next digit in the result. 
Result so far: 2154.13678
If we subtract 6960 from 7100, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 13:
When dividing 1400 by 870, we get 1 with a remainder of 530.
Use 1 as the next digit of our solution. 
Result so far: 2154.136781
If we subtract 870 from 1400, we get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Moving on to step 14:
870 can be fit into 5300 6 times, resulting in a remainder of 80.
The number 6 becomes the next digit in our result. 
Result so far: 2154.1367816
Subtract 5220 from 5300 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 15:
870 goes into 800 0 times with a remainder of 800.
Put 0 as the next digit of the answer. 
Result so far: 2154.1367816
Subtract 0 from 800 to get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

After the division, we end up with 2154.1367816 and a remainder of 8e-07.
