We're dividing 46378426 by 810 
The aim is to understand the frequency of 810 in 46378426.

Advancing to step 1:
4 divided by 810 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 810

Step 2:
If we divide 46 by 810, we get 0 and a remainder of 46.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 46 after subtracting 0 from 46.
Bring next digit (3) of the dividend behind the 46 and repeat the process: 463 / 810

Moving on to step 3:
When dividing 463 by 810, we get 0 with a remainder of 463.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 463 leaves us with 463.
Append the next digit (7) from the dividend to 463 and continue with: 4637 / 810

Advancing to step 4:
If we divide 4637 by 810, we get 5 and a remainder of 587.
The next digit of our result is 5. 
Result so far: 5.0
If we take 4050 away from 4637, we end up with 587.
Grab the next digit (8) from the dividend, add it to 587, then carry on: 5878 / 810

Let's proceed to step 5:
5878 divided by 810 is 7 with a remainder of 208.
The next digit of our result is 7. 
Result so far: 57.0
The remainder is 208 after subtracting 5670 from 5878.
Fetch the next digit (4) from the dividend, attach it to 208 and continue: 2084 / 810

Step 6:
When dividing 2084 by 810, we get 2 with a remainder of 464.
The number 2 becomes the next digit in our result. 
Result so far: 572.0
If we subtract 1620 from 2084, we get 464.
Bring next digit (2) of the dividend behind the 464 and repeat the process: 4642 / 810

Let's proceed to step 7:
4642 divided by 810 is 5 with a remainder of 592.
Use 5 as the next digit of our solution. 
Result so far: 5725.0
If we take 4050 away from 4642, we end up with 592.
Take the next digit (6) from the dividend and append it to 592, then repeat: 5926 / 810

Moving on to step 8:
The number 810 fits into 5926 7 times, leaving a remainder of 256.
Write down 7 as next digit of the result. 
Result so far: 57257.0
The remainder is 256 after subtracting 5670 from 5926.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 9:
810 goes into 2560 3 times with a remainder of 130.
Write down 3 as next digit of the result. 
Result so far: 57257.3
If we take 2430 away from 2560, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 10:
The number 810 fits into 1300 1 times, leaving a remainder of 490.
Put 1 as the next digit of the answer. 
Result so far: 57257.31
If we take 810 away from 1300, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 11:
810 can be fit into 4900 6 times, resulting in a remainder of 40.
The next digit of our result is 6. 
Result so far: 57257.316
Subtracting 4860 from 4900 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
810 can be fit into 400 0 times, resulting in a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 57257.316
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 13:
When dividing 4000 by 810, we get 4 with a remainder of 760.
Record the quotient 4 as the next digit in the result. 
Result so far: 57257.31604
Deduct 3240 from 4000 and we're left with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Moving on to step 14:
810 goes into 7600 9 times with a remainder of 310.
Record the quotient 9 as the next digit in the result. 
Result so far: 57257.316049
Subtracting 7290 from 7600 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 15:
The number 810 fits into 3100 3 times, leaving a remainder of 670.
Write down 3 as next digit of the result. 
Result so far: 57257.3160493
If we take 2430 away from 3100, we end up with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Moving on to step 16:
6700 divided by 810 is 8 with a remainder of 220.
Put 8 as the next digit of the answer. 
Result so far: 57257.31604938
Deduct 6480 from 6700 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

The final outcome is 57257.31604938, with a leftover of 2.2e-07.
