34951638 ÷ 428 
The aim is to understand the frequency of 428 in 34951638.

Let's proceed to step 1:
If we divide 3 by 428, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 428

Step 2:
If we divide 34 by 428, we get 0 and a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Fetch the next digit (9) from the dividend, attach it to 34 and continue: 349 / 428

Step 3:
428 can be fit into 349 0 times, resulting in a remainder of 349.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 349 to get 349.
Grab the next digit (5) from the dividend, add it to 349, then carry on: 3495 / 428

On to step 4:
3495 divided by 428 is 8 with a remainder of 71.
The next digit of our result is 8. 
Result so far: 8.0
If we take 3424 away from 3495, we end up with 71.
Fetch the next digit (1) from the dividend, attach it to 71 and continue: 711 / 428

On to step 5:
428 goes into 711 1 times with a remainder of 283.
Use 1 as the next digit of our solution. 
Result so far: 81.0
If we take 428 away from 711, we end up with 283.
Include the next digit (6) from the dividend after 283, then repeat: 2836 / 428

Moving on to step 6:
When dividing 2836 by 428, we get 6 with a remainder of 268.
Use 6 as the next digit of our solution. 
Result so far: 816.0
If we take 2568 away from 2836, we end up with 268.
Include the next digit (3) from the dividend after 268, then repeat: 2683 / 428

On to step 7:
When dividing 2683 by 428, we get 6 with a remainder of 115.
Record the quotient 6 as the next digit in the result. 
Result so far: 8166.0
Subtract 2568 from 2683 to get 115.
Append the next digit (8) from the dividend to 115 and continue with: 1158 / 428

Let's proceed to step 8:
1158 divided by 428 is 2 with a remainder of 302.
Write down 2 as next digit of the result. 
Result so far: 81662.0
The remainder is 302 after subtracting 856 from 1158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

On to step 9:
428 can be fit into 3020 7 times, resulting in a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 81662.7
Subtract 2996 from 3020 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
If we divide 240 by 428, we get 0 and a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 81662.7
Subtract 0 from 240 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 11:
428 goes into 2400 5 times with a remainder of 260.
Write down 5 as next digit of the result. 
Result so far: 81662.705
If we subtract 2140 from 2400, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 12:
428 goes into 2600 6 times with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 81662.7056
Subtracting 2568 from 2600 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 13:
When dividing 320 by 428, we get 0 with a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 81662.7056
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 14:
If we divide 3200 by 428, we get 7 and a remainder of 204.
Put 7 as the next digit of the answer. 
Result so far: 81662.705607
The remainder is 204 after subtracting 2996 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 15:
428 goes into 2040 4 times with a remainder of 328.
The number 4 becomes the next digit in our result. 
Result so far: 81662.7056074
If we subtract 1712 from 2040, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 16:
When dividing 3280 by 428, we get 7 with a remainder of 284.
The number 7 becomes the next digit in our result. 
Result so far: 81662.70560747
If we subtract 2996 from 3280, we get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

The final outcome is 81662.70560747, with a leftover of 2.84e-07.
