We look at the division of 15157457 by 430 
We're looking to find how many times 430 goes into 15157457.

On to step 1:
If we divide 1 by 430, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 430

Step 2:
If we divide 15 by 430, we get 0 and a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 430

Moving on to step 3:
151 divided by 430 is 0 with a remainder of 151.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 151 leaves us with 151.
Grab the next digit (5) from the dividend, add it to 151, then carry on: 1515 / 430

On to step 4:
If we divide 1515 by 430, we get 3 and a remainder of 225.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 1290 from 1515 and we're left with 225.
Fetch the next digit (7) from the dividend, attach it to 225 and continue: 2257 / 430

Moving on to step 5:
430 can be fit into 2257 5 times, resulting in a remainder of 107.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
If we subtract 2150 from 2257, we get 107.
Bring next digit (4) of the dividend behind the 107 and repeat the process: 1074 / 430

On to step 6:
The number 430 fits into 1074 2 times, leaving a remainder of 214.
The next digit of our result is 2. 
Result so far: 352.0
Subtract 860 from 1074 to get 214.
Take the next digit (5) from the dividend and append it to 214, then repeat: 2145 / 430

Going ahead to step 7:
The number 430 fits into 2145 4 times, leaving a remainder of 425.
Use 4 as the next digit of our solution. 
Result so far: 3524.0
Deduct 1720 from 2145 and we're left with 425.
Take the next digit (7) from the dividend and append it to 425, then repeat: 4257 / 430

Step 8:
If we divide 4257 by 430, we get 9 and a remainder of 387.
The next digit of our result is 9. 
Result so far: 35249.0
Subtracting 3870 from 4257 leaves us with 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Going ahead to step 9:
430 can be fit into 3870 9 times, resulting in a remainder of 0.
The next digit of our result is 9. 
Result so far: 35249.9
Subtract 3870 from 3870 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
When dividing 0 by 430, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 35249.9
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
If we divide 0 by 430, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 35249.9
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 35249.9, with a leftover of 0.0.
