We look at the division of 86548039 by 951 
The aim is to understand the frequency of 951 in 86548039.

Moving on to step 1:
951 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 951

Moving on to step 2:
951 can be fit into 86 0 times, resulting in a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Bring next digit (5) of the dividend behind the 86 and repeat the process: 865 / 951

On to step 3:
951 goes into 865 0 times with a remainder of 865.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 865 leaves us with 865.
Grab the next digit (4) from the dividend, add it to 865, then carry on: 8654 / 951

On to step 4:
If we divide 8654 by 951, we get 9 and a remainder of 95.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 8559 from 8654 and we're left with 95.
Append the next digit (8) from the dividend to 95 and continue with: 958 / 951

Let's proceed to step 5:
958 divided by 951 is 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
Subtracting 951 from 958 leaves us with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 951

Step 6:
If we divide 70 by 951, we get 0 and a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 910.0
Subtracting 0 from 70 leaves us with 70.
Include the next digit (3) from the dividend after 70, then repeat: 703 / 951

Going ahead to step 7:
951 can be fit into 703 0 times, resulting in a remainder of 703.
Write down 0 as next digit of the result. 
Result so far: 9100.0
Deduct 0 from 703 and we're left with 703.
Include the next digit (9) from the dividend after 703, then repeat: 7039 / 951

On to step 8:
951 goes into 7039 7 times with a remainder of 382.
Put 7 as the next digit of the answer. 
Result so far: 91007.0
The remainder is 382 after subtracting 6657 from 7039.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

On to step 9:
951 goes into 3820 4 times with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 91007.4
Subtract 3804 from 3820 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
160 divided by 951 is 0 with a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 91007.4
If we subtract 0 from 160, we 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.

On to step 11:
The number 951 fits into 1600 1 times, leaving a remainder of 649.
Use 1 as the next digit of our solution. 
Result so far: 91007.401
Subtracting 951 from 1600 leaves us with 649.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6490, and continue the process.

Moving on to step 12:
The number 951 fits into 6490 6 times, leaving a remainder of 784.
Use 6 as the next digit of our solution. 
Result so far: 91007.4016
Subtracting 5706 from 6490 leaves us with 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

On to step 13:
When dividing 7840 by 951, we get 8 with a remainder of 232.
Use 8 as the next digit of our solution. 
Result so far: 91007.40168
If we take 7608 away from 7840, we end up with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Let's proceed to step 14:
When dividing 2320 by 951, we get 2 with a remainder of 418.
The number 2 becomes the next digit in our result. 
Result so far: 91007.401682
Subtracting 1902 from 2320 leaves us with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Going ahead to step 15:
951 can be fit into 4180 4 times, resulting in a remainder of 376.
Write down 4 as next digit of the result. 
Result so far: 91007.4016824
The remainder is 376 after subtracting 3804 from 4180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

On to step 16:
3760 divided by 951 is 3 with a remainder of 907.
Put 3 as the next digit of the answer. 
Result so far: 91007.40168243
If we subtract 2853 from 3760, we get 907.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9070, and continue the process.

Our division results in 91007.40168243 with a remaining 9.07e-07.
