We divide 50410739 by 643
The aim is to understand the frequency of 643 in 50410739.

On to step 1:
The number 643 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 643

Moving on to step 2:
When dividing 50 by 643, we get 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Include the next digit (4) from the dividend after 50, then repeat: 504 / 643

Step 3:
When dividing 504 by 643, we get 0 with a remainder of 504.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 504 leaves us with 504.
Take the next digit (1) from the dividend and append it to 504, then repeat: 5041 / 643

Moving on to step 4:
5041 divided by 643 is 7 with a remainder of 540.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 4501 from 5041 and we're left with 540.
Take the next digit (0) from the dividend and append it to 540, then repeat: 5400 / 643

Advancing to step 5:
5400 divided by 643 is 8 with a remainder of 256.
Put 8 as the next digit of the answer. 
Result so far: 78.0
If we take 5144 away from 5400, we end up with 256.
Take the next digit (7) from the dividend and append it to 256, then repeat: 2567 / 643

Going ahead to step 6:
643 can be fit into 2567 3 times, resulting in a remainder of 638.
Put 3 as the next digit of the answer. 
Result so far: 783.0
Deduct 1929 from 2567 and we're left with 638.
Take the next digit (3) from the dividend and append it to 638, then repeat: 6383 / 643

Step 7:
6383 divided by 643 is 9 with a remainder of 596.
Record the quotient 9 as the next digit in the result. 
Result so far: 7839.0
If we take 5787 away from 6383, we end up with 596.
Take the next digit (9) from the dividend and append it to 596, then repeat: 5969 / 643

Step 8:
5969 divided by 643 is 9 with a remainder of 182.
Record the quotient 9 as the next digit in the result. 
Result so far: 78399.0
Deduct 5787 from 5969 and we're left with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Let's proceed to step 9:
The number 643 fits into 1820 2 times, leaving a remainder of 534.
Put 2 as the next digit of the answer. 
Result so far: 78399.2
If we subtract 1286 from 1820, we get 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

On to step 10:
643 can be fit into 5340 8 times, resulting in a remainder of 196.
Write down 8 as next digit of the result. 
Result so far: 78399.28
Subtract 5144 from 5340 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Moving on to step 11:
643 can be fit into 1960 3 times, resulting in a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 78399.283
If we subtract 1929 from 1960, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 12:
643 can be fit into 310 0 times, resulting in a remainder of 310.
Write down 0 as next digit of the result. 
Result so far: 78399.283
Deduct 0 from 310 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 13:
When dividing 3100 by 643, we get 4 with a remainder of 528.
Record the quotient 4 as the next digit in the result. 
Result so far: 78399.28304
Subtracting 2572 from 3100 leaves us with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Going ahead to step 14:
5280 divided by 643 is 8 with a remainder of 136.
Use 8 as the next digit of our solution. 
Result so far: 78399.283048
If we take 5144 away from 5280, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 15:
The number 643 fits into 1360 2 times, leaving a remainder of 74.
Write down 2 as next digit of the result. 
Result so far: 78399.2830482
Subtract 1286 from 1360 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 16:
When dividing 740 by 643, we get 1 with a remainder of 97.
Use 1 as the next digit of our solution. 
Result so far: 78399.28304821
Subtract 643 from 740 to get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Our division results in 78399.28304821 with a remaining 9.7e-08.
