13341171 ÷ 451 
The aim is to understand the frequency of 451 in 13341171.

Step 1:
The number 451 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 451

Step 2:
When dividing 13 by 451, we get 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Bring next digit (3) of the dividend behind the 13 and repeat the process: 133 / 451

Step 3:
133 divided by 451 is 0 with a remainder of 133.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 133 and we're left with 133.
Include the next digit (4) from the dividend after 133, then repeat: 1334 / 451

Going ahead to step 4:
When dividing 1334 by 451, we get 2 with a remainder of 432.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 902 from 1334 to get 432.
Grab the next digit (1) from the dividend, add it to 432, then carry on: 4321 / 451

Moving on to step 5:
When dividing 4321 by 451, we get 9 with a remainder of 262.
Write down 9 as next digit of the result. 
Result so far: 29.0
Subtract 4059 from 4321 to get 262.
Bring next digit (1) of the dividend behind the 262 and repeat the process: 2621 / 451

On to step 6:
If we divide 2621 by 451, we get 5 and a remainder of 366.
The next digit of our result is 5. 
Result so far: 295.0
If we take 2255 away from 2621, we end up with 366.
Grab the next digit (7) from the dividend, add it to 366, then carry on: 3667 / 451

Going ahead to step 7:
When dividing 3667 by 451, we get 8 with a remainder of 59.
The next digit of our result is 8. 
Result so far: 2958.0
Subtracting 3608 from 3667 leaves us with 59.
Grab the next digit (1) from the dividend, add it to 59, then carry on: 591 / 451

Moving on to step 8:
591 divided by 451 is 1 with a remainder of 140.
Write down 1 as next digit of the result. 
Result so far: 29581.0
The remainder is 140 after subtracting 451 from 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 9:
451 can be fit into 1400 3 times, resulting in a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 29581.3
If we subtract 1353 from 1400, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 10:
The number 451 fits into 470 1 times, leaving a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 29581.31
Subtract 451 from 470 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 11:
451 can be fit into 190 0 times, resulting in a remainder of 190.
The number 0 becomes the next digit in our result. 
Result so far: 29581.31
Subtract 0 from 190 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 12:
1900 divided by 451 is 4 with a remainder of 96.
Write down 4 as next digit of the result. 
Result so far: 29581.3104
The remainder is 96 after subtracting 1804 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 13:
If we divide 960 by 451, we get 2 and a remainder of 58.
Write down 2 as next digit of the result. 
Result so far: 29581.31042
Subtract 902 from 960 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 14:
451 goes into 580 1 times with a remainder of 129.
Record the quotient 1 as the next digit in the result. 
Result so far: 29581.310421
Deduct 451 from 580 and we're left with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Step 15:
If we divide 1290 by 451, we get 2 and a remainder of 388.
Use 2 as the next digit of our solution. 
Result so far: 29581.3104212
Deduct 902 from 1290 and we're left with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Moving on to step 16:
The number 451 fits into 3880 8 times, leaving a remainder of 272.
Put 8 as the next digit of the answer. 
Result so far: 29581.31042128
Subtracting 3608 from 3880 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

After the division, we end up with 29581.31042128 and a remainder of 2.72e-07.
