Let's divide 40275959 by 810
The aim is to understand the frequency of 810 in 40275959.

Let's proceed to step 1:
The number 810 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 810

Going ahead to step 2:
810 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Grab the next digit (2) from the dividend, add it to 40, then carry on: 402 / 810

Going ahead to step 3:
If we divide 402 by 810, we get 0 and a remainder of 402.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 402 to get 402.
Bring next digit (7) of the dividend behind the 402 and repeat the process: 4027 / 810

Moving on to step 4:
4027 divided by 810 is 4 with a remainder of 787.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 3240 away from 4027, we end up with 787.
Append the next digit (5) from the dividend to 787 and continue with: 7875 / 810

Step 5:
When dividing 7875 by 810, we get 9 with a remainder of 585.
Put 9 as the next digit of the answer. 
Result so far: 49.0
Subtracting 7290 from 7875 leaves us with 585.
Take the next digit (9) from the dividend and append it to 585, then repeat: 5859 / 810

Let's proceed to step 6:
If we divide 5859 by 810, we get 7 and a remainder of 189.
Write down 7 as next digit of the result. 
Result so far: 497.0
Deduct 5670 from 5859 and we're left with 189.
Grab the next digit (5) from the dividend, add it to 189, then carry on: 1895 / 810

Let's proceed to step 7:
If we divide 1895 by 810, we get 2 and a remainder of 275.
Write down 2 as next digit of the result. 
Result so far: 4972.0
If we take 1620 away from 1895, we end up with 275.
Append the next digit (9) from the dividend to 275 and continue with: 2759 / 810

On to step 8:
2759 divided by 810 is 3 with a remainder of 329.
Use 3 as the next digit of our solution. 
Result so far: 49723.0
If we take 2430 away from 2759, we end up with 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Advancing to step 9:
810 can be fit into 3290 4 times, resulting in a remainder of 50.
Record the quotient 4 as the next digit in the result. 
Result so far: 49723.4
Deduct 3240 from 3290 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
If we divide 500 by 810, we get 0 and a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 49723.4
Subtracting 0 from 500 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 11:
5000 divided by 810 is 6 with a remainder of 140.
Put 6 as the next digit of the answer. 
Result so far: 49723.406
Subtracting 4860 from 5000 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 12:
The number 810 fits into 1400 1 times, leaving a remainder of 590.
The number 1 becomes the next digit in our result. 
Result so far: 49723.4061
Subtracting 810 from 1400 leaves us with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Step 13:
810 can be fit into 5900 7 times, resulting in a remainder of 230.
Use 7 as the next digit of our solution. 
Result so far: 49723.40617
Deduct 5670 from 5900 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 14:
If we divide 2300 by 810, we get 2 and a remainder of 680.
Put 2 as the next digit of the answer. 
Result so far: 49723.406172
If we take 1620 away from 2300, we end up with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Going ahead to step 15:
6800 divided by 810 is 8 with a remainder of 320.
Write down 8 as next digit of the result. 
Result so far: 49723.4061728
If we take 6480 away from 6800, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 16:
810 goes into 3200 3 times with a remainder of 770.
The number 3 becomes the next digit in our result. 
Result so far: 49723.40617283
The remainder is 770 after subtracting 2430 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

After the division, we end up with 49723.40617283 and a remainder of 7.7e-07.
