We look at the division of 68436546 by 472 
The aim is to understand the frequency of 472 in 68436546.

On to step 1:
472 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 472

Advancing to step 2:
When dividing 68 by 472, we get 0 with a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Take the next digit (4) from the dividend and append it to 68, then repeat: 684 / 472

Advancing to step 3:
472 goes into 684 1 times with a remainder of 212.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 472 away from 684, we end up with 212.
Fetch the next digit (3) from the dividend, attach it to 212 and continue: 2123 / 472

Advancing to step 4:
472 can be fit into 2123 4 times, resulting in a remainder of 235.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 1888 from 2123 leaves us with 235.
Append the next digit (6) from the dividend to 235 and continue with: 2356 / 472

Step 5:
472 goes into 2356 4 times with a remainder of 468.
Record the quotient 4 as the next digit in the result. 
Result so far: 144.0
If we subtract 1888 from 2356, we get 468.
Append the next digit (5) from the dividend to 468 and continue with: 4685 / 472

Step 6:
If we divide 4685 by 472, we get 9 and a remainder of 437.
The number 9 becomes the next digit in our result. 
Result so far: 1449.0
The remainder is 437 after subtracting 4248 from 4685.
Fetch the next digit (4) from the dividend, attach it to 437 and continue: 4374 / 472

Advancing to step 7:
If we divide 4374 by 472, we get 9 and a remainder of 126.
The number 9 becomes the next digit in our result. 
Result so far: 14499.0
The remainder is 126 after subtracting 4248 from 4374.
Grab the next digit (6) from the dividend, add it to 126, then carry on: 1266 / 472

Advancing to step 8:
The number 472 fits into 1266 2 times, leaving a remainder of 322.
Put 2 as the next digit of the answer. 
Result so far: 144992.0
Deduct 944 from 1266 and we're left with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

On to step 9:
The number 472 fits into 3220 6 times, leaving a remainder of 388.
The number 6 becomes the next digit in our result. 
Result so far: 144992.6
Subtracting 2832 from 3220 leaves us with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 10:
The number 472 fits into 3880 8 times, leaving a remainder of 104.
Write down 8 as next digit of the result. 
Result so far: 144992.68
Subtracting 3776 from 3880 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 11:
When dividing 1040 by 472, we get 2 with a remainder of 96.
Use 2 as the next digit of our solution. 
Result so far: 144992.682
Subtracting 944 from 1040 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 12:
When dividing 960 by 472, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 144992.6822
Subtract 944 from 960 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 144992.6822 with a remainder of 0.00016.
