13075454 ÷ 428 
Our goal is to divide 13075454 by 428.

Going ahead to step 1:
1 divided by 428 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 428

On to step 2:
The number 428 fits into 13 0 times, leaving a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 428

Step 3:
428 can be fit into 130 0 times, resulting in a remainder of 130.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 130 to get 130.
Bring next digit (7) of the dividend behind the 130 and repeat the process: 1307 / 428

Going ahead to step 4:
If we divide 1307 by 428, we get 3 and a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 1284 away from 1307, we end up with 23.
Fetch the next digit (5) from the dividend, attach it to 23 and continue: 235 / 428

Moving on to step 5:
If we divide 235 by 428, we get 0 and a remainder of 235.
Put 0 as the next digit of the answer. 
Result so far: 30.0
If we take 0 away from 235, we end up with 235.
Fetch the next digit (4) from the dividend, attach it to 235 and continue: 2354 / 428

Step 6:
428 goes into 2354 5 times with a remainder of 214.
Write down 5 as next digit of the result. 
Result so far: 305.0
Subtract 2140 from 2354 to get 214.
Append the next digit (5) from the dividend to 214 and continue with: 2145 / 428

Let's proceed to step 7:
2145 divided by 428 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 3055.0
Subtracting 2140 from 2145 leaves us with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 428

Moving on to step 8:
54 divided by 428 is 0 with a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 30550.0
If we take 0 away from 54, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 9:
428 can be fit into 540 1 times, resulting in a remainder of 112.
Use 1 as the next digit of our solution. 
Result so far: 30550.1
The remainder is 112 after subtracting 428 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 10:
If we divide 1120 by 428, we get 2 and a remainder of 264.
The number 2 becomes the next digit in our result. 
Result so far: 30550.12
If we subtract 856 from 1120, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Moving on to step 11:
428 goes into 2640 6 times with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 30550.126
Deduct 2568 from 2640 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 12:
If we divide 720 by 428, we get 1 and a remainder of 292.
Write down 1 as next digit of the result. 
Result so far: 30550.1261
Subtract 428 from 720 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Going ahead to step 13:
If we divide 2920 by 428, we get 6 and a remainder of 352.
Use 6 as the next digit of our solution. 
Result so far: 30550.12616
Deduct 2568 from 2920 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 14:
If we divide 3520 by 428, we get 8 and a remainder of 96.
The number 8 becomes the next digit in our result. 
Result so far: 30550.126168
If we take 3424 away from 3520, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 15:
When dividing 960 by 428, we get 2 with a remainder of 104.
Put 2 as the next digit of the answer. 
Result so far: 30550.1261682
Deduct 856 from 960 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 16:
The number 428 fits into 1040 2 times, leaving a remainder of 184.
Use 2 as the next digit of our solution. 
Result so far: 30550.12616822
Deduct 856 from 1040 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

The final outcome is 30550.12616822, with a leftover of 1.84e-07.
