86807623 ÷ 954 
The aim is to understand the frequency of 954 in 86807623.

Going ahead to step 1:
8 divided by 954 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 954

Advancing to step 2:
The number 954 fits into 86 0 times, leaving a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Take the next digit (8) from the dividend and append it to 86, then repeat: 868 / 954

Let's proceed to step 3:
When dividing 868 by 954, we get 0 with a remainder of 868.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 868 and we're left with 868.
Fetch the next digit (0) from the dividend, attach it to 868 and continue: 8680 / 954

Advancing to step 4:
The number 954 fits into 8680 9 times, leaving a remainder of 94.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 8586 away from 8680, we end up with 94.
Fetch the next digit (7) from the dividend, attach it to 94 and continue: 947 / 954

Advancing to step 5:
954 can be fit into 947 0 times, resulting in a remainder of 947.
Use 0 as the next digit of our solution. 
Result so far: 90.0
Deduct 0 from 947 and we're left with 947.
Bring next digit (6) of the dividend behind the 947 and repeat the process: 9476 / 954

On to step 6:
9476 divided by 954 is 9 with a remainder of 890.
The next digit of our result is 9. 
Result so far: 909.0
The remainder is 890 after subtracting 8586 from 9476.
Include the next digit (2) from the dividend after 890, then repeat: 8902 / 954

Advancing to step 7:
The number 954 fits into 8902 9 times, leaving a remainder of 316.
Put 9 as the next digit of the answer. 
Result so far: 9099.0
Subtracting 8586 from 8902 leaves us with 316.
Take the next digit (3) from the dividend and append it to 316, then repeat: 3163 / 954

Going ahead to step 8:
If we divide 3163 by 954, we get 3 and a remainder of 301.
Use 3 as the next digit of our solution. 
Result so far: 90993.0
If we take 2862 away from 3163, we end up with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

On to step 9:
3010 divided by 954 is 3 with a remainder of 148.
Use 3 as the next digit of our solution. 
Result so far: 90993.3
Deduct 2862 from 3010 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 10:
954 goes into 1480 1 times with a remainder of 526.
Record the quotient 1 as the next digit in the result. 
Result so far: 90993.31
If we subtract 954 from 1480, we get 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

On to step 11:
954 goes into 5260 5 times with a remainder of 490.
Put 5 as the next digit of the answer. 
Result so far: 90993.315
Subtracting 4770 from 5260 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Going ahead to step 12:
The number 954 fits into 4900 5 times, leaving a remainder of 130.
The next digit of our result is 5. 
Result so far: 90993.3155
Subtracting 4770 from 4900 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

The final result is 90993.3155 with a remainder of 0.0013.
