81538032 divided by 951 
The aim is to understand the frequency of 951 in 81538032.

Let's proceed to step 1:
8 divided by 951 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 951

Moving on to step 2:
951 goes into 81 0 times with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Take the next digit (5) from the dividend and append it to 81, then repeat: 815 / 951

Moving on to step 3:
951 can be fit into 815 0 times, resulting in a remainder of 815.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 815 and we're left with 815.
Take the next digit (3) from the dividend and append it to 815, then repeat: 8153 / 951

On to step 4:
When dividing 8153 by 951, we get 8 with a remainder of 545.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 7608 from 8153 to get 545.
Take the next digit (8) from the dividend and append it to 545, then repeat: 5458 / 951

Advancing to step 5:
5458 divided by 951 is 5 with a remainder of 703.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
Subtract 4755 from 5458 to get 703.
Include the next digit (0) from the dividend after 703, then repeat: 7030 / 951

Advancing to step 6:
951 can be fit into 7030 7 times, resulting in a remainder of 373.
The next digit of our result is 7. 
Result so far: 857.0
If we take 6657 away from 7030, we end up with 373.
Include the next digit (3) from the dividend after 373, then repeat: 3733 / 951

Advancing to step 7:
The number 951 fits into 3733 3 times, leaving a remainder of 880.
Write down 3 as next digit of the result. 
Result so far: 8573.0
The remainder is 880 after subtracting 2853 from 3733.
Append the next digit (2) from the dividend to 880 and continue with: 8802 / 951

Going ahead to step 8:
8802 divided by 951 is 9 with a remainder of 243.
The number 9 becomes the next digit in our result. 
Result so far: 85739.0
Subtract 8559 from 8802 to get 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Let's proceed to step 9:
951 goes into 2430 2 times with a remainder of 528.
Record the quotient 2 as the next digit in the result. 
Result so far: 85739.2
Deduct 1902 from 2430 and we're left with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Going ahead to step 10:
The number 951 fits into 5280 5 times, leaving a remainder of 525.
Record the quotient 5 as the next digit in the result. 
Result so far: 85739.25
Subtracting 4755 from 5280 leaves us with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Moving on to step 11:
If we divide 5250 by 951, we get 5 and a remainder of 495.
Write down 5 as next digit of the result. 
Result so far: 85739.255
Deduct 4755 from 5250 and we're left with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

After the division, we end up with 85739.255 and a remainder of 0.0495.
