We divide 35207265 by 643
The aim is to understand the frequency of 643 in 35207265.

On to step 1:
3 divided by 643 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 643

On to step 2:
643 can be fit into 35 0 times, resulting in a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Include the next digit (2) from the dividend after 35, then repeat: 352 / 643

Moving on to step 3:
When dividing 352 by 643, we get 0 with a remainder of 352.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 352, we get 352.
Bring next digit (0) of the dividend behind the 352 and repeat the process: 3520 / 643

On to step 4:
3520 divided by 643 is 5 with a remainder of 305.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 3215 from 3520 and we're left with 305.
Grab the next digit (7) from the dividend, add it to 305, then carry on: 3057 / 643

Going ahead to step 5:
643 goes into 3057 4 times with a remainder of 485.
Put 4 as the next digit of the answer. 
Result so far: 54.0
Subtracting 2572 from 3057 leaves us with 485.
Include the next digit (2) from the dividend after 485, then repeat: 4852 / 643

Going ahead to step 6:
643 can be fit into 4852 7 times, resulting in a remainder of 351.
The number 7 becomes the next digit in our result. 
Result so far: 547.0
Subtract 4501 from 4852 to get 351.
Include the next digit (6) from the dividend after 351, then repeat: 3516 / 643

Going ahead to step 7:
643 goes into 3516 5 times with a remainder of 301.
Put 5 as the next digit of the answer. 
Result so far: 5475.0
Subtract 3215 from 3516 to get 301.
Bring next digit (5) of the dividend behind the 301 and repeat the process: 3015 / 643

Advancing to step 8:
When dividing 3015 by 643, we get 4 with a remainder of 443.
Write down 4 as next digit of the result. 
Result so far: 54754.0
If we take 2572 away from 3015, we end up with 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Moving on to step 9:
If we divide 4430 by 643, we get 6 and a remainder of 572.
Record the quotient 6 as the next digit in the result. 
Result so far: 54754.6
The remainder is 572 after subtracting 3858 from 4430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Step 10:
5720 divided by 643 is 8 with a remainder of 576.
Record the quotient 8 as the next digit in the result. 
Result so far: 54754.68
Deduct 5144 from 5720 and we're left with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Let's proceed to step 11:
The number 643 fits into 5760 8 times, leaving a remainder of 616.
The next digit of our result is 8. 
Result so far: 54754.688
If we subtract 5144 from 5760, we get 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Our division results in 54754.688 with a remaining 0.0616.
