We're dividing 91856673 by 870 
The aim is to understand the frequency of 870 in 91856673.

On to step 1:
When dividing 9 by 870, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 870

Step 2:
870 can be fit into 91 0 times, resulting in a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Include the next digit (8) from the dividend after 91, then repeat: 918 / 870

On to step 3:
918 divided by 870 is 1 with a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 870 from 918 and we're left with 48.
Bring next digit (5) of the dividend behind the 48 and repeat the process: 485 / 870

Let's proceed to step 4:
485 divided by 870 is 0 with a remainder of 485.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 485, we end up with 485.
Append the next digit (6) from the dividend to 485 and continue with: 4856 / 870

Moving on to step 5:
870 can be fit into 4856 5 times, resulting in a remainder of 506.
Use 5 as the next digit of our solution. 
Result so far: 105.0
Subtracting 4350 from 4856 leaves us with 506.
Append the next digit (6) from the dividend to 506 and continue with: 5066 / 870

Advancing to step 6:
The number 870 fits into 5066 5 times, leaving a remainder of 716.
Use 5 as the next digit of our solution. 
Result so far: 1055.0
If we subtract 4350 from 5066, we get 716.
Include the next digit (7) from the dividend after 716, then repeat: 7167 / 870

On to step 7:
870 goes into 7167 8 times with a remainder of 207.
Use 8 as the next digit of our solution. 
Result so far: 10558.0
If we subtract 6960 from 7167, we get 207.
Take the next digit (3) from the dividend and append it to 207, then repeat: 2073 / 870

Advancing to step 8:
If we divide 2073 by 870, we get 2 and a remainder of 333.
Put 2 as the next digit of the answer. 
Result so far: 105582.0
Subtracting 1740 from 2073 leaves us with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Step 9:
If we divide 3330 by 870, we get 3 and a remainder of 720.
Use 3 as the next digit of our solution. 
Result so far: 105582.3
Subtract 2610 from 3330 to get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Moving on to step 10:
The number 870 fits into 7200 8 times, leaving a remainder of 240.
The next digit of our result is 8. 
Result so far: 105582.38
The remainder is 240 after subtracting 6960 from 7200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 11:
870 goes into 2400 2 times with a remainder of 660.
The next digit of our result is 2. 
Result so far: 105582.382
Deduct 1740 from 2400 and we're left with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Advancing to step 12:
870 goes into 6600 7 times with a remainder of 510.
Put 7 as the next digit of the answer. 
Result so far: 105582.3827
The remainder is 510 after subtracting 6090 from 6600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Step 13:
870 can be fit into 5100 5 times, resulting in a remainder of 750.
The next digit of our result is 5. 
Result so far: 105582.38275
Subtract 4350 from 5100 to get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Step 14:
If we divide 7500 by 870, we get 8 and a remainder of 540.
Write down 8 as next digit of the result. 
Result so far: 105582.382758
Subtract 6960 from 7500 to get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Let's proceed to step 15:
5400 divided by 870 is 6 with a remainder of 180.
The next digit of our result is 6. 
Result so far: 105582.3827586
If we take 5220 away from 5400, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 16:
1800 divided by 870 is 2 with a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 105582.38275862
The remainder is 60 after subtracting 1740 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 105582.38275862, and the remainder is 6e-08.
