We divide 400428 by 69
The aim is to understand the frequency of 69 in 400428.

Moving on to step 1:
When dividing 4 by 69, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 69

Going ahead to step 2:
If we divide 40 by 69, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Bring next digit (0) of the dividend behind the 40 and repeat the process: 400 / 69

On to step 3:
400 divided by 69 is 5 with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 345 from 400 and we're left with 55.
Append the next digit (4) from the dividend to 55 and continue with: 554 / 69

Going ahead to step 4:
69 goes into 554 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 58.0
If we take 552 away from 554, we end up with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 69

Moving on to step 5:
When dividing 22 by 69, we get 0 with a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 580.0
If we subtract 0 from 22, we get 22.
Fetch the next digit (8) from the dividend, attach it to 22 and continue: 228 / 69

Advancing to step 6:
69 can be fit into 228 3 times, resulting in a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 5803.0
Subtract 207 from 228 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
When dividing 210 by 69, we get 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 5803.3
The remainder is 3 after subtracting 207 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 8:
The number 69 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 5803.3
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
If we divide 300 by 69, we get 4 and a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 5803.304
Deduct 276 from 300 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
240 divided by 69 is 3 with a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 5803.3043
The remainder is 33 after subtracting 207 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 11:
When dividing 330 by 69, we get 4 with a remainder of 54.
Put 4 as the next digit of the answer. 
Result so far: 5803.30434
The remainder is 54 after subtracting 276 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 12:
69 goes into 540 7 times with a remainder of 57.
The number 7 becomes the next digit in our result. 
Result so far: 5803.304347
Subtracting 483 from 540 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 13:
69 goes into 570 8 times with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 5803.3043478
The remainder is 18 after subtracting 552 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 14:
When dividing 180 by 69, we get 2 with a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 5803.30434782
If we take 138 away from 180, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

After the division, we end up with 5803.30434782 and a remainder of 4.2e-08.
