36317591 ÷ 451 
The aim is to understand the frequency of 451 in 36317591.

Moving on to step 1:
The number 451 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 451

Advancing to step 2:
451 can be fit into 36 0 times, resulting in a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 36 and we're left with 36.
Include the next digit (3) from the dividend after 36, then repeat: 363 / 451

On to step 3:
451 goes into 363 0 times with a remainder of 363.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 363 and we're left with 363.
Include the next digit (1) from the dividend after 363, then repeat: 3631 / 451

Moving on to step 4:
The number 451 fits into 3631 8 times, leaving a remainder of 23.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 23 after subtracting 3608 from 3631.
Include the next digit (7) from the dividend after 23, then repeat: 237 / 451

Let's proceed to step 5:
When dividing 237 by 451, we get 0 with a remainder of 237.
Put 0 as the next digit of the answer. 
Result so far: 80.0
If we take 0 away from 237, we end up with 237.
Append the next digit (5) from the dividend to 237 and continue with: 2375 / 451

On to step 6:
2375 divided by 451 is 5 with a remainder of 120.
Record the quotient 5 as the next digit in the result. 
Result so far: 805.0
Subtract 2255 from 2375 to get 120.
Append the next digit (9) from the dividend to 120 and continue with: 1209 / 451

Step 7:
1209 divided by 451 is 2 with a remainder of 307.
The next digit of our result is 2. 
Result so far: 8052.0
Deduct 902 from 1209 and we're left with 307.
Fetch the next digit (1) from the dividend, attach it to 307 and continue: 3071 / 451

Going ahead to step 8:
When dividing 3071 by 451, we get 6 with a remainder of 365.
Put 6 as the next digit of the answer. 
Result so far: 80526.0
If we subtract 2706 from 3071, we get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Step 9:
451 can be fit into 3650 8 times, resulting in a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 80526.8
Deduct 3608 from 3650 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 10:
If we divide 420 by 451, we get 0 and a remainder of 420.
Use 0 as the next digit of our solution. 
Result so far: 80526.8
If we subtract 0 from 420, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 11:
451 goes into 4200 9 times with a remainder of 141.
Record the quotient 9 as the next digit in the result. 
Result so far: 80526.809
If we take 4059 away from 4200, we end up with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Moving on to step 12:
When dividing 1410 by 451, we get 3 with a remainder of 57.
Put 3 as the next digit of the answer. 
Result so far: 80526.8093
If we subtract 1353 from 1410, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 13:
451 goes into 570 1 times with a remainder of 119.
Record the quotient 1 as the next digit in the result. 
Result so far: 80526.80931
The remainder is 119 after subtracting 451 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Moving on to step 14:
The number 451 fits into 1190 2 times, leaving a remainder of 288.
Write down 2 as next digit of the result. 
Result so far: 80526.809312
Deduct 902 from 1190 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Let's proceed to step 15:
451 can be fit into 2880 6 times, resulting in a remainder of 174.
Put 6 as the next digit of the answer. 
Result so far: 80526.8093126
Subtract 2706 from 2880 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Step 16:
If we divide 1740 by 451, we get 3 and a remainder of 387.
Put 3 as the next digit of the answer. 
Result so far: 80526.80931263
If we subtract 1353 from 1740, we get 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Our division results in 80526.80931263 with a remaining 3.87e-07.
