4254981 divided by 428 
The aim is to understand the frequency of 428 in 4254981.

Moving on to step 1:
4 divided by 428 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 428

On to step 2:
428 can be fit into 42 0 times, resulting in a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Append the next digit (5) from the dividend to 42 and continue with: 425 / 428

On to step 3:
425 divided by 428 is 0 with a remainder of 425.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 425 leaves us with 425.
Take the next digit (4) from the dividend and append it to 425, then repeat: 4254 / 428

On to step 4:
428 goes into 4254 9 times with a remainder of 402.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 3852 away from 4254, we end up with 402.
Bring next digit (9) of the dividend behind the 402 and repeat the process: 4029 / 428

Going ahead to step 5:
428 can be fit into 4029 9 times, resulting in a remainder of 177.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
If we take 3852 away from 4029, we end up with 177.
Fetch the next digit (8) from the dividend, attach it to 177 and continue: 1778 / 428

Step 6:
428 can be fit into 1778 4 times, resulting in a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 994.0
If we subtract 1712 from 1778, we get 66.
Take the next digit (1) from the dividend and append it to 66, then repeat: 661 / 428

Advancing to step 7:
428 can be fit into 661 1 times, resulting in a remainder of 233.
Put 1 as the next digit of the answer. 
Result so far: 9941.0
If we subtract 428 from 661, we get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Moving on to step 8:
The number 428 fits into 2330 5 times, leaving a remainder of 190.
Put 5 as the next digit of the answer. 
Result so far: 9941.5
If we take 2140 away from 2330, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 9:
428 can be fit into 1900 4 times, resulting in a remainder of 188.
Put 4 as the next digit of the answer. 
Result so far: 9941.54
If we take 1712 away from 1900, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 10:
When dividing 1880 by 428, we get 4 with a remainder of 168.
Put 4 as the next digit of the answer. 
Result so far: 9941.544
If we subtract 1712 from 1880, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Our division results in 9941.544 with a remaining 0.0168.
