10287762 divided by 870 
The aim is to understand the frequency of 870 in 10287762.

On to step 1:
When dividing 1 by 870, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 870

Advancing to step 2:
870 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 870

Advancing to step 3:
The number 870 fits into 102 0 times, leaving a remainder of 102.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 102 to get 102.
Bring next digit (8) of the dividend behind the 102 and repeat the process: 1028 / 870

Moving on to step 4:
If we divide 1028 by 870, we get 1 and a remainder of 158.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 870 from 1028 leaves us with 158.
Grab the next digit (7) from the dividend, add it to 158, then carry on: 1587 / 870

Advancing to step 5:
If we divide 1587 by 870, we get 1 and a remainder of 717.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 870 from 1587, we get 717.
Include the next digit (7) from the dividend after 717, then repeat: 7177 / 870

Let's proceed to step 6:
The number 870 fits into 7177 8 times, leaving a remainder of 217.
The next digit of our result is 8. 
Result so far: 118.0
Subtracting 6960 from 7177 leaves us with 217.
Append the next digit (6) from the dividend to 217 and continue with: 2176 / 870

Let's proceed to step 7:
When dividing 2176 by 870, we get 2 with a remainder of 436.
The number 2 becomes the next digit in our result. 
Result so far: 1182.0
Deduct 1740 from 2176 and we're left with 436.
Include the next digit (2) from the dividend after 436, then repeat: 4362 / 870

Moving on to step 8:
870 goes into 4362 5 times with a remainder of 12.
The next digit of our result is 5. 
Result so far: 11825.0
Deduct 4350 from 4362 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 9:
When dividing 120 by 870, we get 0 with a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 11825.0
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 10:
1200 divided by 870 is 1 with a remainder of 330.
Write down 1 as next digit of the result. 
Result so far: 11825.01
Deduct 870 from 1200 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 11:
870 can be fit into 3300 3 times, resulting in a remainder of 690.
Put 3 as the next digit of the answer. 
Result so far: 11825.013
Deduct 2610 from 3300 and we're left with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Let's proceed to step 12:
870 can be fit into 6900 7 times, resulting in a remainder of 810.
Write down 7 as next digit of the result. 
Result so far: 11825.0137
If we take 6090 away from 6900, we end up with 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Advancing to step 13:
8100 divided by 870 is 9 with a remainder of 270.
Use 9 as the next digit of our solution. 
Result so far: 11825.01379
If we take 7830 away from 8100, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 14:
When dividing 2700 by 870, we get 3 with a remainder of 90.
Use 3 as the next digit of our solution. 
Result so far: 11825.013793
Deduct 2610 from 2700 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 15:
When dividing 900 by 870, we get 1 with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 11825.0137931
Deduct 870 from 900 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 16:
The number 870 fits into 300 0 times, leaving a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 11825.0137931
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

In conclusion, the division gives 11825.0137931 with a balance of 3e-07.
