We're dividing 1258248 by 647 
The aim is to understand the frequency of 647 in 1258248.

Advancing to step 1:
If we divide 1 by 647, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 647

On to step 2:
647 goes into 12 0 times with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 647

Advancing to step 3:
647 can be fit into 125 0 times, resulting in a remainder of 125.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 125 and we're left with 125.
Grab the next digit (8) from the dividend, add it to 125, then carry on: 1258 / 647

Going ahead to step 4:
If we divide 1258 by 647, we get 1 and a remainder of 611.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 647 from 1258 and we're left with 611.
Grab the next digit (2) from the dividend, add it to 611, then carry on: 6112 / 647

Step 5:
If we divide 6112 by 647, we get 9 and a remainder of 289.
The next digit of our result is 9. 
Result so far: 19.0
If we subtract 5823 from 6112, we get 289.
Grab the next digit (4) from the dividend, add it to 289, then carry on: 2894 / 647

Going ahead to step 6:
647 goes into 2894 4 times with a remainder of 306.
The number 4 becomes the next digit in our result. 
Result so far: 194.0
If we subtract 2588 from 2894, we get 306.
Take the next digit (8) from the dividend and append it to 306, then repeat: 3068 / 647

On to step 7:
The number 647 fits into 3068 4 times, leaving a remainder of 480.
The next digit of our result is 4. 
Result so far: 1944.0
Deduct 2588 from 3068 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 8:
If we divide 4800 by 647, we get 7 and a remainder of 271.
Use 7 as the next digit of our solution. 
Result so far: 1944.7
Subtracting 4529 from 4800 leaves us with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Advancing to step 9:
If we divide 2710 by 647, we get 4 and a remainder of 122.
Write down 4 as next digit of the result. 
Result so far: 1944.74
If we subtract 2588 from 2710, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Step 10:
The number 647 fits into 1220 1 times, leaving a remainder of 573.
Record the quotient 1 as the next digit in the result. 
Result so far: 1944.741
Subtract 647 from 1220 to get 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Let's proceed to step 11:
If we divide 5730 by 647, we get 8 and a remainder of 554.
Write down 8 as next digit of the result. 
Result so far: 1944.7418
The remainder is 554 after subtracting 5176 from 5730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Moving on to step 12:
The number 647 fits into 5540 8 times, leaving a remainder of 364.
Write down 8 as next digit of the result. 
Result so far: 1944.74188
If we take 5176 away from 5540, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

The quotient of the division is 1944.74188, and the remainder is 0.000364.
