Let's divide 80403185 by 851
The aim is to understand the frequency of 851 in 80403185.

Advancing to step 1:
851 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 851

Step 2:
When dividing 80 by 851, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Grab the next digit (4) from the dividend, add it to 80, then carry on: 804 / 851

Moving on to step 3:
851 can be fit into 804 0 times, resulting in a remainder of 804.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 804 to get 804.
Grab the next digit (0) from the dividend, add it to 804, then carry on: 8040 / 851

Let's proceed to step 4:
8040 divided by 851 is 9 with a remainder of 381.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 7659 from 8040 leaves us with 381.
Grab the next digit (3) from the dividend, add it to 381, then carry on: 3813 / 851

Going ahead to step 5:
If we divide 3813 by 851, we get 4 and a remainder of 409.
The number 4 becomes the next digit in our result. 
Result so far: 94.0
Deduct 3404 from 3813 and we're left with 409.
Fetch the next digit (1) from the dividend, attach it to 409 and continue: 4091 / 851

On to step 6:
If we divide 4091 by 851, we get 4 and a remainder of 687.
Put 4 as the next digit of the answer. 
Result so far: 944.0
Deduct 3404 from 4091 and we're left with 687.
Append the next digit (8) from the dividend to 687 and continue with: 6878 / 851

Step 7:
When dividing 6878 by 851, we get 8 with a remainder of 70.
The next digit of our result is 8. 
Result so far: 9448.0
If we subtract 6808 from 6878, we get 70.
Take the next digit (5) from the dividend and append it to 70, then repeat: 705 / 851

Advancing to step 8:
The number 851 fits into 705 0 times, leaving a remainder of 705.
Record the quotient 0 as the next digit in the result. 
Result so far: 94480.0
Subtracting 0 from 705 leaves us with 705.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

Let's proceed to step 9:
851 can be fit into 7050 8 times, resulting in a remainder of 242.
Record the quotient 8 as the next digit in the result. 
Result so far: 94480.8
If we take 6808 away from 7050, we end up with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Let's proceed to step 10:
The number 851 fits into 2420 2 times, leaving a remainder of 718.
Write down 2 as next digit of the result. 
Result so far: 94480.82
If we take 1702 away from 2420, we end up with 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

Let's proceed to step 11:
The number 851 fits into 7180 8 times, leaving a remainder of 372.
Use 8 as the next digit of our solution. 
Result so far: 94480.828
Subtract 6808 from 7180 to get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

On to step 12:
3720 divided by 851 is 4 with a remainder of 316.
The next digit of our result is 4. 
Result so far: 94480.8284
If we take 3404 away from 3720, we end up with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 13:
851 can be fit into 3160 3 times, resulting in a remainder of 607.
The number 3 becomes the next digit in our result. 
Result so far: 94480.82843
If we take 2553 away from 3160, we end up with 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Moving on to step 14:
851 goes into 6070 7 times with a remainder of 113.
Use 7 as the next digit of our solution. 
Result so far: 94480.828437
If we take 5957 away from 6070, we end up with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Moving on to step 15:
When dividing 1130 by 851, we get 1 with a remainder of 279.
Put 1 as the next digit of the answer. 
Result so far: 94480.8284371
The remainder is 279 after subtracting 851 from 1130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Going ahead to step 16:
851 can be fit into 2790 3 times, resulting in a remainder of 237.
Record the quotient 3 as the next digit in the result. 
Result so far: 94480.82843713
Subtracting 2553 from 2790 leaves us with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Our division results in 94480.82843713 with a remaining 2.37e-07.
