We look at the division of 98018351 by 807 
The aim is to understand the frequency of 807 in 98018351.

Let's proceed to step 1:
If we divide 9 by 807, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 807

Step 2:
98 divided by 807 is 0 with a remainder of 98.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 98 after subtracting 0 from 98.
Fetch the next digit (0) from the dividend, attach it to 98 and continue: 980 / 807

Moving on to step 3:
When dividing 980 by 807, we get 1 with a remainder of 173.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 807 from 980 leaves us with 173.
Include the next digit (1) from the dividend after 173, then repeat: 1731 / 807

Step 4:
The number 807 fits into 1731 2 times, leaving a remainder of 117.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 1614 from 1731 to get 117.
Take the next digit (8) from the dividend and append it to 117, then repeat: 1178 / 807

Moving on to step 5:
The number 807 fits into 1178 1 times, leaving a remainder of 371.
The number 1 becomes the next digit in our result. 
Result so far: 121.0
If we take 807 away from 1178, we end up with 371.
Take the next digit (3) from the dividend and append it to 371, then repeat: 3713 / 807

Going ahead to step 6:
807 goes into 3713 4 times with a remainder of 485.
Use 4 as the next digit of our solution. 
Result so far: 1214.0
Subtract 3228 from 3713 to get 485.
Bring next digit (5) of the dividend behind the 485 and repeat the process: 4855 / 807

Let's proceed to step 7:
807 goes into 4855 6 times with a remainder of 13.
Put 6 as the next digit of the answer. 
Result so far: 12146.0
Subtracting 4842 from 4855 leaves us with 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 807

On to step 8:
807 can be fit into 131 0 times, resulting in a remainder of 131.
Record the quotient 0 as the next digit in the result. 
Result so far: 121460.0
The remainder is 131 after subtracting 0 from 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Moving on to step 9:
807 can be fit into 1310 1 times, resulting in a remainder of 503.
Put 1 as the next digit of the answer. 
Result so far: 121460.1
The remainder is 503 after subtracting 807 from 1310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Advancing to step 10:
807 goes into 5030 6 times with a remainder of 188.
The next digit of our result is 6. 
Result so far: 121460.16
The remainder is 188 after subtracting 4842 from 5030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 11:
807 can be fit into 1880 2 times, resulting in a remainder of 266.
Write down 2 as next digit of the result. 
Result so far: 121460.162
The remainder is 266 after subtracting 1614 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Moving on to step 12:
If we divide 2660 by 807, we get 3 and a remainder of 239.
Use 3 as the next digit of our solution. 
Result so far: 121460.1623
Subtracting 2421 from 2660 leaves us with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Moving on to step 13:
When dividing 2390 by 807, we get 2 with a remainder of 776.
The next digit of our result is 2. 
Result so far: 121460.16232
Deduct 1614 from 2390 and we're left with 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

Let's proceed to step 14:
If we divide 7760 by 807, we get 9 and a remainder of 497.
The number 9 becomes the next digit in our result. 
Result so far: 121460.162329
Deduct 7263 from 7760 and we're left with 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

Let's proceed to step 15:
If we divide 4970 by 807, we get 6 and a remainder of 128.
Put 6 as the next digit of the answer. 
Result so far: 121460.1623296
Deduct 4842 from 4970 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 16:
807 goes into 1280 1 times with a remainder of 473.
Record the quotient 1 as the next digit in the result. 
Result so far: 121460.16232961
Subtracting 807 from 1280 leaves us with 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

The quotient of the division is 121460.16232961, and the remainder is 4.73e-07.
