We divide 35431620 by 811
The aim is to understand the frequency of 811 in 35431620.

Step 1:
811 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 811

Let's proceed to step 2:
The number 811 fits into 35 0 times, leaving a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Append the next digit (4) from the dividend to 35 and continue with: 354 / 811

On to step 3:
811 can be fit into 354 0 times, resulting in a remainder of 354.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 354 after subtracting 0 from 354.
Take the next digit (3) from the dividend and append it to 354, then repeat: 3543 / 811

Moving on to step 4:
The number 811 fits into 3543 4 times, leaving a remainder of 299.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 3244 away from 3543, we end up with 299.
Include the next digit (1) from the dividend after 299, then repeat: 2991 / 811

Advancing to step 5:
811 goes into 2991 3 times with a remainder of 558.
The next digit of our result is 3. 
Result so far: 43.0
If we take 2433 away from 2991, we end up with 558.
Fetch the next digit (6) from the dividend, attach it to 558 and continue: 5586 / 811

Going ahead to step 6:
The number 811 fits into 5586 6 times, leaving a remainder of 720.
Record the quotient 6 as the next digit in the result. 
Result so far: 436.0
If we subtract 4866 from 5586, we get 720.
Append the next digit (2) from the dividend to 720 and continue with: 7202 / 811

On to step 7:
If we divide 7202 by 811, we get 8 and a remainder of 714.
The next digit of our result is 8. 
Result so far: 4368.0
If we take 6488 away from 7202, we end up with 714.
Fetch the next digit (0) from the dividend, attach it to 714 and continue: 7140 / 811

Moving on to step 8:
If we divide 7140 by 811, we get 8 and a remainder of 652.
Use 8 as the next digit of our solution. 
Result so far: 43688.0
If we take 6488 away from 7140, we end up with 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Moving on to step 9:
811 can be fit into 6520 8 times, resulting in a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 43688.8
Subtract 6488 from 6520 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
When dividing 320 by 811, we get 0 with a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 43688.8
If we take 0 away from 320, 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.

On to step 11:
The number 811 fits into 3200 3 times, leaving a remainder of 767.
Put 3 as the next digit of the answer. 
Result so far: 43688.803
If we subtract 2433 from 3200, we get 767.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7670, and continue the process.

On to step 12:
If we divide 7670 by 811, we get 9 and a remainder of 371.
Write down 9 as next digit of the result. 
Result so far: 43688.8039
The remainder is 371 after subtracting 7299 from 7670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Step 13:
If we divide 3710 by 811, we get 4 and a remainder of 466.
The next digit of our result is 4. 
Result so far: 43688.80394
Subtract 3244 from 3710 to get 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Advancing to step 14:
811 goes into 4660 5 times with a remainder of 605.
The next digit of our result is 5. 
Result so far: 43688.803945
Subtracting 4055 from 4660 leaves us with 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Let's proceed to step 15:
6050 divided by 811 is 7 with a remainder of 373.
Put 7 as the next digit of the answer. 
Result so far: 43688.8039457
If we take 5677 away from 6050, we end up with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Step 16:
If we divide 3730 by 811, we get 4 and a remainder of 486.
Use 4 as the next digit of our solution. 
Result so far: 43688.80394574
Deduct 3244 from 3730 and we're left with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Our division results in 43688.80394574 with a remaining 4.86e-07.
