We divide 18940562 by 428
The aim is to understand the frequency of 428 in 18940562.

Step 1:
If we divide 1 by 428, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 428

Step 2:
If we divide 18 by 428, we get 0 and a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 428

Let's proceed to step 3:
428 goes into 189 0 times with a remainder of 189.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 189, we get 189.
Grab the next digit (4) from the dividend, add it to 189, then carry on: 1894 / 428

Going ahead to step 4:
The number 428 fits into 1894 4 times, leaving a remainder of 182.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 1712 from 1894 and we're left with 182.
Grab the next digit (0) from the dividend, add it to 182, then carry on: 1820 / 428

Moving on to step 5:
1820 divided by 428 is 4 with a remainder of 108.
Write down 4 as next digit of the result. 
Result so far: 44.0
The remainder is 108 after subtracting 1712 from 1820.
Take the next digit (5) from the dividend and append it to 108, then repeat: 1085 / 428

Moving on to step 6:
428 can be fit into 1085 2 times, resulting in a remainder of 229.
Use 2 as the next digit of our solution. 
Result so far: 442.0
If we subtract 856 from 1085, we get 229.
Append the next digit (6) from the dividend to 229 and continue with: 2296 / 428

On to step 7:
428 can be fit into 2296 5 times, resulting in a remainder of 156.
Put 5 as the next digit of the answer. 
Result so far: 4425.0
If we subtract 2140 from 2296, we get 156.
Grab the next digit (2) from the dividend, add it to 156, then carry on: 1562 / 428

Advancing to step 8:
The number 428 fits into 1562 3 times, leaving a remainder of 278.
The number 3 becomes the next digit in our result. 
Result so far: 44253.0
Subtract 1284 from 1562 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Advancing to step 9:
When dividing 2780 by 428, we get 6 with a remainder of 212.
The next digit of our result is 6. 
Result so far: 44253.6
Subtract 2568 from 2780 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 10:
428 goes into 2120 4 times with a remainder of 408.
Use 4 as the next digit of our solution. 
Result so far: 44253.64
If we take 1712 away from 2120, we end up with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Going ahead to step 11:
When dividing 4080 by 428, we get 9 with a remainder of 228.
The next digit of our result is 9. 
Result so far: 44253.649
Subtracting 3852 from 4080 leaves us with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Advancing to step 12:
428 can be fit into 2280 5 times, resulting in a remainder of 140.
Put 5 as the next digit of the answer. 
Result so far: 44253.6495
If we subtract 2140 from 2280, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 13:
The number 428 fits into 1400 3 times, leaving a remainder of 116.
The next digit of our result is 3. 
Result so far: 44253.64953
If we subtract 1284 from 1400, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Advancing to step 14:
If we divide 1160 by 428, we get 2 and a remainder of 304.
The next digit of our result is 2. 
Result so far: 44253.649532
If we take 856 away from 1160, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 15:
When dividing 3040 by 428, we get 7 with a remainder of 44.
The next digit of our result is 7. 
Result so far: 44253.6495327
Subtracting 2996 from 3040 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 16:
The number 428 fits into 440 1 times, leaving a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 44253.64953271
If we take 428 away from 440, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 44253.64953271 with a remaining 1.2e-08.
