Let's divide 35486382 by 645
The aim is to understand the frequency of 645 in 35486382.

Moving on to step 1:
645 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 645

Advancing to step 2:
35 divided by 645 is 0 with a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Fetch the next digit (4) from the dividend, attach it to 35 and continue: 354 / 645

Going ahead to step 3:
The number 645 fits into 354 0 times, leaving 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 (8) from the dividend and append it to 354, then repeat: 3548 / 645

Moving on to step 4:
645 can be fit into 3548 5 times, resulting in a remainder of 323.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 3225 away from 3548, we end up with 323.
Append the next digit (6) from the dividend to 323 and continue with: 3236 / 645

Let's proceed to step 5:
645 can be fit into 3236 5 times, resulting in a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 55.0
Deduct 3225 from 3236 and we're left with 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 645

Step 6:
If we divide 113 by 645, we get 0 and a remainder of 113.
The number 0 becomes the next digit in our result. 
Result so far: 550.0
Deduct 0 from 113 and we're left with 113.
Grab the next digit (8) from the dividend, add it to 113, then carry on: 1138 / 645

Going ahead to step 7:
645 goes into 1138 1 times with a remainder of 493.
Record the quotient 1 as the next digit in the result. 
Result so far: 5501.0
Deduct 645 from 1138 and we're left with 493.
Append the next digit (2) from the dividend to 493 and continue with: 4932 / 645

Let's proceed to step 8:
645 can be fit into 4932 7 times, resulting in a remainder of 417.
The next digit of our result is 7. 
Result so far: 55017.0
Subtracting 4515 from 4932 leaves us with 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Advancing to step 9:
If we divide 4170 by 645, we get 6 and a remainder of 300.
Put 6 as the next digit of the answer. 
Result so far: 55017.6
Subtract 3870 from 4170 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 10:
3000 divided by 645 is 4 with a remainder of 420.
Record the quotient 4 as the next digit in the result. 
Result so far: 55017.64
If we take 2580 away from 3000, we end up with 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:
If we divide 4200 by 645, we get 6 and a remainder of 330.
Use 6 as the next digit of our solution. 
Result so far: 55017.646
Subtracting 3870 from 4200 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 12:
The number 645 fits into 3300 5 times, leaving a remainder of 75.
The next digit of our result is 5. 
Result so far: 55017.6465
Subtract 3225 from 3300 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 13:
750 divided by 645 is 1 with a remainder of 105.
The next digit of our result is 1. 
Result so far: 55017.64651
If we subtract 645 from 750, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 14:
645 can be fit into 1050 1 times, resulting in a remainder of 405.
Put 1 as the next digit of the answer. 
Result so far: 55017.646511
The remainder is 405 after subtracting 645 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

The final outcome is 55017.646511, with a leftover of 4.05e-05.
