4956171 ÷ 426 
The aim is to understand the frequency of 426 in 4956171.

Moving on to step 1:
If we divide 4 by 426, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 426

On to step 2:
The number 426 fits into 49 0 times, leaving a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 49 after subtracting 0 from 49.
Append the next digit (5) from the dividend to 49 and continue with: 495 / 426

Moving on to step 3:
495 divided by 426 is 1 with a remainder of 69.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 426 from 495, we get 69.
Include the next digit (6) from the dividend after 69, then repeat: 696 / 426

Step 4:
696 divided by 426 is 1 with a remainder of 270.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 426 away from 696, we end up with 270.
Take the next digit (1) from the dividend and append it to 270, then repeat: 2701 / 426

On to step 5:
When dividing 2701 by 426, we get 6 with a remainder of 145.
Write down 6 as next digit of the result. 
Result so far: 116.0
If we subtract 2556 from 2701, we get 145.
Take the next digit (7) from the dividend and append it to 145, then repeat: 1457 / 426

Going ahead to step 6:
If we divide 1457 by 426, we get 3 and a remainder of 179.
The number 3 becomes the next digit in our result. 
Result so far: 1163.0
Deduct 1278 from 1457 and we're left with 179.
Take the next digit (1) from the dividend and append it to 179, then repeat: 1791 / 426

On to step 7:
1791 divided by 426 is 4 with a remainder of 87.
Record the quotient 4 as the next digit in the result. 
Result so far: 11634.0
If we subtract 1704 from 1791, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 8:
426 can be fit into 870 2 times, resulting in a remainder of 18.
The next digit of our result is 2. 
Result so far: 11634.2
The remainder is 18 after subtracting 852 from 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
If we divide 180 by 426, we get 0 and a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 11634.2
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 10:
When dividing 1800 by 426, we get 4 with a remainder of 96.
Put 4 as the next digit of the answer. 
Result so far: 11634.204
The remainder is 96 after subtracting 1704 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 11:
426 goes into 960 2 times with a remainder of 108.
Record the quotient 2 as the next digit in the result. 
Result so far: 11634.2042
The remainder is 108 after subtracting 852 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 12:
426 goes into 1080 2 times with a remainder of 228.
The next digit of our result is 2. 
Result so far: 11634.20422
Subtract 852 from 1080 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

The quotient of the division is 11634.20422, and the remainder is 0.000228.
