33781993 ÷ 651 
The aim is to understand the frequency of 651 in 33781993.

Let's proceed to step 1:
The number 651 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 651

Advancing to step 2:
The number 651 fits into 33 0 times, leaving a remainder of 33.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 33 leaves us with 33.
Take the next digit (7) from the dividend and append it to 33, then repeat: 337 / 651

On to step 3:
If we divide 337 by 651, we get 0 and a remainder of 337.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 337 after subtracting 0 from 337.
Bring next digit (8) of the dividend behind the 337 and repeat the process: 3378 / 651

Moving on to step 4:
When dividing 3378 by 651, we get 5 with a remainder of 123.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 3255 away from 3378, we end up with 123.
Include the next digit (1) from the dividend after 123, then repeat: 1231 / 651

Moving on to step 5:
If we divide 1231 by 651, we get 1 and a remainder of 580.
Use 1 as the next digit of our solution. 
Result so far: 51.0
Deduct 651 from 1231 and we're left with 580.
Fetch the next digit (9) from the dividend, attach it to 580 and continue: 5809 / 651

Advancing to step 6:
When dividing 5809 by 651, we get 8 with a remainder of 601.
Use 8 as the next digit of our solution. 
Result so far: 518.0
If we subtract 5208 from 5809, we get 601.
Grab the next digit (9) from the dividend, add it to 601, then carry on: 6019 / 651

Going ahead to step 7:
651 can be fit into 6019 9 times, resulting in a remainder of 160.
Put 9 as the next digit of the answer. 
Result so far: 5189.0
The remainder is 160 after subtracting 5859 from 6019.
Grab the next digit (3) from the dividend, add it to 160, then carry on: 1603 / 651

Step 8:
1603 divided by 651 is 2 with a remainder of 301.
Use 2 as the next digit of our solution. 
Result so far: 51892.0
Deduct 1302 from 1603 and we're left with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Going ahead to step 9:
The number 651 fits into 3010 4 times, leaving a remainder of 406.
The number 4 becomes the next digit in our result. 
Result so far: 51892.4
Subtract 2604 from 3010 to get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Step 10:
4060 divided by 651 is 6 with a remainder of 154.
The number 6 becomes the next digit in our result. 
Result so far: 51892.46
Subtract 3906 from 4060 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Advancing to step 11:
1540 divided by 651 is 2 with a remainder of 238.
Record the quotient 2 as the next digit in the result. 
Result so far: 51892.462
Subtract 1302 from 1540 to get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Moving on to step 12:
If we divide 2380 by 651, we get 3 and a remainder of 427.
Use 3 as the next digit of our solution. 
Result so far: 51892.4623
If we take 1953 away from 2380, we end up with 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

Advancing to step 13:
When dividing 4270 by 651, we get 6 with a remainder of 364.
Record the quotient 6 as the next digit in the result. 
Result so far: 51892.46236
The remainder is 364 after subtracting 3906 from 4270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Advancing to step 14:
3640 divided by 651 is 5 with a remainder of 385.
The number 5 becomes the next digit in our result. 
Result so far: 51892.462365
If we take 3255 away from 3640, we end up with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Step 15:
When dividing 3850 by 651, we get 5 with a remainder of 595.
The next digit of our result is 5. 
Result so far: 51892.4623655
Subtracting 3255 from 3850 leaves us with 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

After the division, we end up with 51892.4623655 and a remainder of 5.95e-06.
