61643091 ÷ 867 
The aim is to understand the frequency of 867 in 61643091.

Going ahead to step 1:
867 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 867

On to step 2:
The number 867 fits into 61 0 times, leaving a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 61 leaves us with 61.
Grab the next digit (6) from the dividend, add it to 61, then carry on: 616 / 867

On to step 3:
If we divide 616 by 867, we get 0 and a remainder of 616.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 616 to get 616.
Include the next digit (4) from the dividend after 616, then repeat: 6164 / 867

On to step 4:
If we divide 6164 by 867, we get 7 and a remainder of 95.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 6069 away from 6164, we end up with 95.
Include the next digit (3) from the dividend after 95, then repeat: 953 / 867

Moving on to step 5:
When dividing 953 by 867, we get 1 with a remainder of 86.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
Deduct 867 from 953 and we're left with 86.
Bring next digit (0) of the dividend behind the 86 and repeat the process: 860 / 867

Step 6:
867 goes into 860 0 times with a remainder of 860.
The next digit of our result is 0. 
Result so far: 710.0
Subtracting 0 from 860 leaves us with 860.
Fetch the next digit (9) from the dividend, attach it to 860 and continue: 8609 / 867

On to step 7:
867 goes into 8609 9 times with a remainder of 806.
Record the quotient 9 as the next digit in the result. 
Result so far: 7109.0
The remainder is 806 after subtracting 7803 from 8609.
Take the next digit (1) from the dividend and append it to 806, then repeat: 8061 / 867

Step 8:
8061 divided by 867 is 9 with a remainder of 258.
The number 9 becomes the next digit in our result. 
Result so far: 71099.0
If we take 7803 away from 8061, we end up with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Let's proceed to step 9:
2580 divided by 867 is 2 with a remainder of 846.
Record the quotient 2 as the next digit in the result. 
Result so far: 71099.2
Deduct 1734 from 2580 and we're left with 846.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8460, and continue the process.

Going ahead to step 10:
The number 867 fits into 8460 9 times, leaving a remainder of 657.
The number 9 becomes the next digit in our result. 
Result so far: 71099.29
Deduct 7803 from 8460 and we're left with 657.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6570, and continue the process.

Step 11:
The number 867 fits into 6570 7 times, leaving a remainder of 501.
Record the quotient 7 as the next digit in the result. 
Result so far: 71099.297
If we subtract 6069 from 6570, we get 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

On to step 12:
When dividing 5010 by 867, we get 5 with a remainder of 675.
The number 5 becomes the next digit in our result. 
Result so far: 71099.2975
Subtract 4335 from 5010 to get 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Let's proceed to step 13:
6750 divided by 867 is 7 with a remainder of 681.
Use 7 as the next digit of our solution. 
Result so far: 71099.29757
Deduct 6069 from 6750 and we're left with 681.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6810, and continue the process.

On to step 14:
If we divide 6810 by 867, we get 7 and a remainder of 741.
The next digit of our result is 7. 
Result so far: 71099.297577
If we subtract 6069 from 6810, we get 741.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7410, and continue the process.

Our division results in 71099.297577 with a remaining 7.41e-05.
