71160268 divided by 643 
The aim is to understand the frequency of 643 in 71160268.

Let's proceed to step 1:
643 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 643

Advancing to step 2:
643 goes into 71 0 times with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Bring next digit (1) of the dividend behind the 71 and repeat the process: 711 / 643

Going ahead to step 3:
The number 643 fits into 711 1 times, leaving a remainder of 68.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 643 from 711, we get 68.
Bring next digit (6) of the dividend behind the 68 and repeat the process: 686 / 643

Moving on to step 4:
686 divided by 643 is 1 with a remainder of 43.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 43 after subtracting 643 from 686.
Take the next digit (0) from the dividend and append it to 43, then repeat: 430 / 643

Going ahead to step 5:
The number 643 fits into 430 0 times, leaving a remainder of 430.
Put 0 as the next digit of the answer. 
Result so far: 110.0
Subtracting 0 from 430 leaves us with 430.
Bring next digit (2) of the dividend behind the 430 and repeat the process: 4302 / 643

Going ahead to step 6:
4302 divided by 643 is 6 with a remainder of 444.
Use 6 as the next digit of our solution. 
Result so far: 1106.0
The remainder is 444 after subtracting 3858 from 4302.
Take the next digit (6) from the dividend and append it to 444, then repeat: 4446 / 643

Advancing to step 7:
The number 643 fits into 4446 6 times, leaving a remainder of 588.
The next digit of our result is 6. 
Result so far: 11066.0
If we take 3858 away from 4446, we end up with 588.
Append the next digit (8) from the dividend to 588 and continue with: 5888 / 643

Moving on to step 8:
5888 divided by 643 is 9 with a remainder of 101.
Put 9 as the next digit of the answer. 
Result so far: 110669.0
The remainder is 101 after subtracting 5787 from 5888.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Let's proceed to step 9:
1010 divided by 643 is 1 with a remainder of 367.
The next digit of our result is 1. 
Result so far: 110669.1
If we subtract 643 from 1010, we get 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Going ahead to step 10:
3670 divided by 643 is 5 with a remainder of 455.
Write down 5 as next digit of the result. 
Result so far: 110669.15
The remainder is 455 after subtracting 3215 from 3670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Let's proceed to step 11:
4550 divided by 643 is 7 with a remainder of 49.
Put 7 as the next digit of the answer. 
Result so far: 110669.157
Subtract 4501 from 4550 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 12:
When dividing 490 by 643, we get 0 with a remainder of 490.
Put 0 as the next digit of the answer. 
Result so far: 110669.157
If we subtract 0 from 490, we get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Moving on to step 13:
The number 643 fits into 4900 7 times, leaving a remainder of 399.
The next digit of our result is 7. 
Result so far: 110669.15707
Subtracting 4501 from 4900 leaves us with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Going ahead to step 14:
The number 643 fits into 3990 6 times, leaving a remainder of 132.
Record the quotient 6 as the next digit in the result. 
Result so far: 110669.157076
Subtract 3858 from 3990 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 15:
1320 divided by 643 is 2 with a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 110669.1570762
Subtracting 1286 from 1320 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 16:
643 goes into 340 0 times with a remainder of 340.
The next digit of our result is 0. 
Result so far: 110669.1570762
If we subtract 0 from 340, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

After the division, we end up with 110669.1570762 and a remainder of 3.4e-07.
