71588272 divided by 428 
The aim is to understand the frequency of 428 in 71588272.

Advancing to step 1:
7 divided by 428 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 428

Step 2:
428 can be fit into 71 0 times, resulting in a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Fetch the next digit (5) from the dividend, attach it to 71 and continue: 715 / 428

Let's proceed to step 3:
428 can be fit into 715 1 times, resulting in a remainder of 287.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 287 after subtracting 428 from 715.
Grab the next digit (8) from the dividend, add it to 287, then carry on: 2878 / 428

Step 4:
2878 divided by 428 is 6 with a remainder of 310.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtracting 2568 from 2878 leaves us with 310.
Bring next digit (8) of the dividend behind the 310 and repeat the process: 3108 / 428

Let's proceed to step 5:
428 can be fit into 3108 7 times, resulting in a remainder of 112.
Use 7 as the next digit of our solution. 
Result so far: 167.0
Subtracting 2996 from 3108 leaves us with 112.
Fetch the next digit (2) from the dividend, attach it to 112 and continue: 1122 / 428

Step 6:
If we divide 1122 by 428, we get 2 and a remainder of 266.
Write down 2 as next digit of the result. 
Result so far: 1672.0
If we take 856 away from 1122, we end up with 266.
Fetch the next digit (7) from the dividend, attach it to 266 and continue: 2667 / 428

On to step 7:
2667 divided by 428 is 6 with a remainder of 99.
Use 6 as the next digit of our solution. 
Result so far: 16726.0
Deduct 2568 from 2667 and we're left with 99.
Append the next digit (2) from the dividend to 99 and continue with: 992 / 428

Moving on to step 8:
If we divide 992 by 428, we get 2 and a remainder of 136.
Record the quotient 2 as the next digit in the result. 
Result so far: 167262.0
Subtract 856 from 992 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 9:
1360 divided by 428 is 3 with a remainder of 76.
Put 3 as the next digit of the answer. 
Result so far: 167262.3
Subtract 1284 from 1360 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 10:
760 divided by 428 is 1 with a remainder of 332.
Write down 1 as next digit of the result. 
Result so far: 167262.31
The remainder is 332 after subtracting 428 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Advancing to step 11:
If we divide 3320 by 428, we get 7 and a remainder of 324.
Put 7 as the next digit of the answer. 
Result so far: 167262.317
If we take 2996 away from 3320, we end up with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Step 12:
If we divide 3240 by 428, we get 7 and a remainder of 244.
Write down 7 as next digit of the result. 
Result so far: 167262.3177
The remainder is 244 after subtracting 2996 from 3240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

The final result is 167262.3177 with a remainder of 0.00244.
