Let's divide 63842881 by 870
The aim is to understand the frequency of 870 in 63842881.

Step 1:
The number 870 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 870

On to step 2:
The number 870 fits into 63 0 times, leaving a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Take the next digit (8) from the dividend and append it to 63, then repeat: 638 / 870

On to step 3:
The number 870 fits into 638 0 times, leaving a remainder of 638.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 638 to get 638.
Include the next digit (4) from the dividend after 638, then repeat: 6384 / 870

Let's proceed to step 4:
If we divide 6384 by 870, we get 7 and a remainder of 294.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 6090 from 6384 to get 294.
Bring next digit (2) of the dividend behind the 294 and repeat the process: 2942 / 870

On to step 5:
2942 divided by 870 is 3 with a remainder of 332.
Put 3 as the next digit of the answer. 
Result so far: 73.0
If we subtract 2610 from 2942, we get 332.
Append the next digit (8) from the dividend to 332 and continue with: 3328 / 870

Let's proceed to step 6:
870 goes into 3328 3 times with a remainder of 718.
Write down 3 as next digit of the result. 
Result so far: 733.0
Deduct 2610 from 3328 and we're left with 718.
Take the next digit (8) from the dividend and append it to 718, then repeat: 7188 / 870

Moving on to step 7:
870 goes into 7188 8 times with a remainder of 228.
Use 8 as the next digit of our solution. 
Result so far: 7338.0
Subtract 6960 from 7188 to get 228.
Fetch the next digit (1) from the dividend, attach it to 228 and continue: 2281 / 870

Step 8:
2281 divided by 870 is 2 with a remainder of 541.
Record the quotient 2 as the next digit in the result. 
Result so far: 73382.0
Deduct 1740 from 2281 and we're left with 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Moving on to step 9:
870 goes into 5410 6 times with a remainder of 190.
Use 6 as the next digit of our solution. 
Result so far: 73382.6
Deduct 5220 from 5410 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 10:
If we divide 1900 by 870, we get 2 and a remainder of 160.
The number 2 becomes the next digit in our result. 
Result so far: 73382.62
Subtract 1740 from 1900 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 11:
870 goes into 1600 1 times with a remainder of 730.
Write down 1 as next digit of the result. 
Result so far: 73382.621
If we take 870 away from 1600, we end up with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Going ahead to step 12:
When dividing 7300 by 870, we get 8 with a remainder of 340.
Record the quotient 8 as the next digit in the result. 
Result so far: 73382.6218
If we subtract 6960 from 7300, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 13:
3400 divided by 870 is 3 with a remainder of 790.
Write down 3 as next digit of the result. 
Result so far: 73382.62183
If we subtract 2610 from 3400, we get 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Let's proceed to step 14:
7900 divided by 870 is 9 with a remainder of 70.
Write down 9 as next digit of the result. 
Result so far: 73382.621839
Subtracting 7830 from 7900 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 15:
870 can be fit into 700 0 times, resulting in a remainder of 700.
Use 0 as the next digit of our solution. 
Result so far: 73382.621839
If we take 0 away from 700, we end up with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

On to step 16:
If we divide 7000 by 870, we get 8 and a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 73382.62183908
If we take 6960 away from 7000, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 73382.62183908 with a remainder of 4e-08.
