We divide 71755726 by 807
The aim is to understand the frequency of 807 in 71755726.

Step 1:
7 divided by 807 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 807

Let's proceed to step 2:
If we divide 71 by 807, we get 0 and a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Fetch the next digit (7) from the dividend, attach it to 71 and continue: 717 / 807

Advancing to step 3:
When dividing 717 by 807, we get 0 with a remainder of 717.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 717, we end up with 717.
Append the next digit (5) from the dividend to 717 and continue with: 7175 / 807

On to step 4:
If we divide 7175 by 807, we get 8 and a remainder of 719.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 6456 away from 7175, we end up with 719.
Include the next digit (5) from the dividend after 719, then repeat: 7195 / 807

On to step 5:
807 goes into 7195 8 times with a remainder of 739.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
The remainder is 739 after subtracting 6456 from 7195.
Fetch the next digit (7) from the dividend, attach it to 739 and continue: 7397 / 807

Going ahead to step 6:
7397 divided by 807 is 9 with a remainder of 134.
The next digit of our result is 9. 
Result so far: 889.0
If we subtract 7263 from 7397, we get 134.
Bring next digit (2) of the dividend behind the 134 and repeat the process: 1342 / 807

Step 7:
807 goes into 1342 1 times with a remainder of 535.
Use 1 as the next digit of our solution. 
Result so far: 8891.0
If we subtract 807 from 1342, we get 535.
Append the next digit (6) from the dividend to 535 and continue with: 5356 / 807

Let's proceed to step 8:
5356 divided by 807 is 6 with a remainder of 514.
The next digit of our result is 6. 
Result so far: 88916.0
If we subtract 4842 from 5356, we get 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Going ahead to step 9:
807 can be fit into 5140 6 times, resulting in a remainder of 298.
Use 6 as the next digit of our solution. 
Result so far: 88916.6
Subtracting 4842 from 5140 leaves us with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Going ahead to step 10:
If we divide 2980 by 807, we get 3 and a remainder of 559.
The next digit of our result is 3. 
Result so far: 88916.63
If we subtract 2421 from 2980, we get 559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

Moving on to step 11:
When dividing 5590 by 807, we get 6 with a remainder of 748.
The number 6 becomes the next digit in our result. 
Result so far: 88916.636
If we take 4842 away from 5590, we end up with 748.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7480, and continue the process.

Going ahead to step 12:
When dividing 7480 by 807, we get 9 with a remainder of 217.
Put 9 as the next digit of the answer. 
Result so far: 88916.6369
Subtracting 7263 from 7480 leaves us with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

On to step 13:
When dividing 2170 by 807, we get 2 with a remainder of 556.
Use 2 as the next digit of our solution. 
Result so far: 88916.63692
If we take 1614 away from 2170, we end up with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Step 14:
807 can be fit into 5560 6 times, resulting in a remainder of 718.
Write down 6 as next digit of the result. 
Result so far: 88916.636926
Subtract 4842 from 5560 to get 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

On to step 15:
807 can be fit into 7180 8 times, resulting in a remainder of 724.
The number 8 becomes the next digit in our result. 
Result so far: 88916.6369268
If we subtract 6456 from 7180, we get 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Moving on to step 16:
When dividing 7240 by 807, we get 8 with a remainder of 784.
The number 8 becomes the next digit in our result. 
Result so far: 88916.63692688
Subtract 6456 from 7240 to get 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

After the division, we end up with 88916.63692688 and a remainder of 7.84e-07.
