67536507 divided by 851 
The aim is to understand the frequency of 851 in 67536507.

Let's proceed to step 1:
851 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 851

On to step 2:
If we divide 67 by 851, we get 0 and a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Take the next digit (5) from the dividend and append it to 67, then repeat: 675 / 851

On to step 3:
851 can be fit into 675 0 times, resulting in a remainder of 675.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 675 leaves us with 675.
Bring next digit (3) of the dividend behind the 675 and repeat the process: 6753 / 851

Moving on to step 4:
851 can be fit into 6753 7 times, resulting in a remainder of 796.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 5957 from 6753, we get 796.
Grab the next digit (6) from the dividend, add it to 796, then carry on: 7966 / 851

Step 5:
When dividing 7966 by 851, we get 9 with a remainder of 307.
Put 9 as the next digit of the answer. 
Result so far: 79.0
If we take 7659 away from 7966, we end up with 307.
Include the next digit (5) from the dividend after 307, then repeat: 3075 / 851

Going ahead to step 6:
The number 851 fits into 3075 3 times, leaving a remainder of 522.
The number 3 becomes the next digit in our result. 
Result so far: 793.0
If we subtract 2553 from 3075, we get 522.
Append the next digit (0) from the dividend to 522 and continue with: 5220 / 851

On to step 7:
When dividing 5220 by 851, we get 6 with a remainder of 114.
Put 6 as the next digit of the answer. 
Result so far: 7936.0
The remainder is 114 after subtracting 5106 from 5220.
Take the next digit (7) from the dividend and append it to 114, then repeat: 1147 / 851

Moving on to step 8:
851 can be fit into 1147 1 times, resulting in a remainder of 296.
The number 1 becomes the next digit in our result. 
Result so far: 79361.0
The remainder is 296 after subtracting 851 from 1147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 9:
When dividing 2960 by 851, we get 3 with a remainder of 407.
Use 3 as the next digit of our solution. 
Result so far: 79361.3
The remainder is 407 after subtracting 2553 from 2960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Going ahead to step 10:
4070 divided by 851 is 4 with a remainder of 666.
Write down 4 as next digit of the result. 
Result so far: 79361.34
Deduct 3404 from 4070 and we're left with 666.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

Step 11:
When dividing 6660 by 851, we get 7 with a remainder of 703.
Put 7 as the next digit of the answer. 
Result so far: 79361.347
The remainder is 703 after subtracting 5957 from 6660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7030, and continue the process.

Moving on to step 12:
The number 851 fits into 7030 8 times, leaving a remainder of 222.
The number 8 becomes the next digit in our result. 
Result so far: 79361.3478
The remainder is 222 after subtracting 6808 from 7030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Step 13:
851 goes into 2220 2 times with a remainder of 518.
Write down 2 as next digit of the result. 
Result so far: 79361.34782
Deduct 1702 from 2220 and we're left with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Let's proceed to step 14:
When dividing 5180 by 851, we get 6 with a remainder of 74.
Put 6 as the next digit of the answer. 
Result so far: 79361.347826
If we subtract 5106 from 5180, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 15:
851 can be fit into 740 0 times, resulting in a remainder of 740.
The number 0 becomes the next digit in our result. 
Result so far: 79361.347826
The remainder is 740 after subtracting 0 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Let's proceed to step 16:
If we divide 7400 by 851, we get 8 and a remainder of 592.
Record the quotient 8 as the next digit in the result. 
Result so far: 79361.34782608
If we subtract 6808 from 7400, we get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

After the division, we end up with 79361.34782608 and a remainder of 5.92e-07.
