Fetch the next digit (5) from the dividend, attach it to 234 and continue: 2345 / 428

Going ahead to step 5:
When dividing 2345 by 428, we get 5 with a remainder of 205.
Write down 5 as next digit of the result. 
Result so far: 95.0
Deduct 2140 from 2345 and we're left with 205.
Append the next digit (0) from the dividend to 205 and continue with: 2050 / 428

Let's proceed to step 6:
428 can be fit into 2050 4 times, resulting in a remainder of 338.
Record the quotient 4 as the next digit in the result. 
Result so far: 954.0
Deduct 1712 from 2050 and we're left with 338.
Include the next digit (8) from the dividend after 338, then repeat: 3388 / 428

Moving on to step 7:
If we divide 3388 by 428, we get 7 and a remainder of 392.
The number 7 becomes the next digit in our result. 
Result so far: 9547.0
Subtract 2996 from 3388 to get 392.
Append the next digit (6) from the dividend to 392 and continue with: 3926 / 428

On to step 8:
428 can be fit into 3926 9 times, resulting in a remainder of 74.
The next digit of our result is 9. 
Result so far: 95479.0
If we subtract 3852 from 3926, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 9:
If we divide 740 by 428, we get 1 and a remainder of 312.
The number 1 becomes the next digit in our result. 
Result so far: 95479.1
If we subtract 428 from 740, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

On to step 10:
428 goes into 3120 7 times with a remainder of 124.
Use 7 as the next digit of our solution. 
Result so far: 95479.17
Deduct 2996 from 3120 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Let's proceed to step 11:
If we divide 1240 by 428, we get 2 and a remainder of 384.
The next digit of our result is 2. 
Result so far: 95479.172
The remainder is 384 after subtracting 856 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Moving on to step 12:
The number 428 fits into 3840 8 times, leaving a remainder of 416.
Put 8 as the next digit of the answer. 
Result so far: 95479.1728
Deduct 3424 from 3840 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 13:
4160 divided by 428 is 9 with a remainder of 308.
The number 9 becomes the next digit in our result. 
Result so far: 95479.17289
The remainder is 308 after subtracting 3852 from 4160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

On to step 14:
3080 divided by 428 is 7 with a remainder of 84.
Use 7 as the next digit of our solution. 
Result so far: 95479.172897
Subtracting 2996 from 3080 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 15:
When dividing 840 by 428, we get 1 with a remainder of 412.
Record the quotient 1 as the next digit in the result. 
Result so far: 95479.1728971
Subtracting 428 from 840 leaves us with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Let's proceed to step 16:
The number 428 fits into 4120 9 times, leaving a remainder of 268.
The number 9 becomes the next digit in our result. 
Result so far: 95479.17289719
Subtracting 3852 from 4120 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

The final outcome is 95479.17289719, with a leftover of 2.68e-07.
