Let's divide 87928457 by 807
The aim is to understand the frequency of 807 in 87928457.

Advancing to step 1:
If we divide 8 by 807, we get 0 and 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.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 807

Moving on to step 2:
When dividing 87 by 807, we get 0 with a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Take the next digit (9) from the dividend and append it to 87, then repeat: 879 / 807

Let's proceed to step 3:
When dividing 879 by 807, we get 1 with a remainder of 72.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 807 away from 879, we end up with 72.
Append the next digit (2) from the dividend to 72 and continue with: 722 / 807

Let's proceed to step 4:
If we divide 722 by 807, we get 0 and a remainder of 722.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 722 leaves us with 722.
Bring next digit (8) of the dividend behind the 722 and repeat the process: 7228 / 807

Moving on to step 5:
7228 divided by 807 is 8 with a remainder of 772.
The next digit of our result is 8. 
Result so far: 108.0
Subtract 6456 from 7228 to get 772.
Bring next digit (4) of the dividend behind the 772 and repeat the process: 7724 / 807

On to step 6:
If we divide 7724 by 807, we get 9 and a remainder of 461.
Put 9 as the next digit of the answer. 
Result so far: 1089.0
The remainder is 461 after subtracting 7263 from 7724.
Append the next digit (5) from the dividend to 461 and continue with: 4615 / 807

Moving on to step 7:
807 goes into 4615 5 times with a remainder of 580.
Write down 5 as next digit of the result. 
Result so far: 10895.0
Subtract 4035 from 4615 to get 580.
Include the next digit (7) from the dividend after 580, then repeat: 5807 / 807

Step 8:
5807 divided by 807 is 7 with a remainder of 158.
Put 7 as the next digit of the answer. 
Result so far: 108957.0
Deduct 5649 from 5807 and we're left with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Going ahead to step 9:
807 can be fit into 1580 1 times, resulting in a remainder of 773.
The next digit of our result is 1. 
Result so far: 108957.1
If we subtract 807 from 1580, we get 773.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7730, and continue the process.

Step 10:
7730 divided by 807 is 9 with a remainder of 467.
Use 9 as the next digit of our solution. 
Result so far: 108957.19
Deduct 7263 from 7730 and we're left with 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Let's proceed to step 11:
If we divide 4670 by 807, we get 5 and a remainder of 635.
The next digit of our result is 5. 
Result so far: 108957.195
Subtracting 4035 from 4670 leaves us with 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Going ahead to step 12:
When dividing 6350 by 807, we get 7 with a remainder of 701.
The next digit of our result is 7. 
Result so far: 108957.1957
The remainder is 701 after subtracting 5649 from 6350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7010, and continue the process.

Advancing to step 13:
When dividing 7010 by 807, we get 8 with a remainder of 554.
The number 8 becomes the next digit in our result. 
Result so far: 108957.19578
If we take 6456 away from 7010, we end up with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Moving on to step 14:
807 goes into 5540 6 times with a remainder of 698.
Write down 6 as next digit of the result. 
Result so far: 108957.195786
If we subtract 4842 from 5540, we get 698.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

On to step 15:
The number 807 fits into 6980 8 times, leaving a remainder of 524.
Write down 8 as next digit of the result. 
Result so far: 108957.1957868
The remainder is 524 after subtracting 6456 from 6980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Let's proceed to step 16:
When dividing 5240 by 807, we get 6 with a remainder of 398.
Record the quotient 6 as the next digit in the result. 
Result so far: 108957.19578686
Subtracting 4842 from 5240 leaves us with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

The final outcome is 108957.19578686, with a leftover of 3.98e-07.
