We're dividing 15188260 by 350 
Let's see how many times 350 fits into 15188260.

Step 1:
350 goes into 1 0 times 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 (5) from the dividend, add it to 1, then carry on: 15 / 350

Advancing to step 2:
350 can be fit into 15 0 times, resulting in 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 / 350

On to step 3:
151 divided by 350 is 0 with a remainder of 151.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 151 leaves us with 151.
Grab the next digit (8) from the dividend, add it to 151, then carry on: 1518 / 350

On to step 4:
When dividing 1518 by 350, we get 4 with a remainder of 118.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 1400 from 1518 and we're left with 118.
Bring next digit (8) of the dividend behind the 118 and repeat the process: 1188 / 350

Moving on to step 5:
If we divide 1188 by 350, we get 3 and a remainder of 138.
Write down 3 as next digit of the result. 
Result so far: 43.0
The remainder is 138 after subtracting 1050 from 1188.
Grab the next digit (2) from the dividend, add it to 138, then carry on: 1382 / 350

On to step 6:
350 can be fit into 1382 3 times, resulting in a remainder of 332.
Record the quotient 3 as the next digit in the result. 
Result so far: 433.0
Deduct 1050 from 1382 and we're left with 332.
Append the next digit (6) from the dividend to 332 and continue with: 3326 / 350

Going ahead to step 7:
The number 350 fits into 3326 9 times, leaving a remainder of 176.
Record the quotient 9 as the next digit in the result. 
Result so far: 4339.0
Subtract 3150 from 3326 to get 176.
Append the next digit (0) from the dividend to 176 and continue with: 1760 / 350

Going ahead to step 8:
When dividing 1760 by 350, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 43395.0
Subtracting 1750 from 1760 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
When dividing 100 by 350, we get 0 with a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 43395.0
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 10:
If we divide 1000 by 350, we get 2 and a remainder of 300.
Put 2 as the next digit of the answer. 
Result so far: 43395.02
If we take 700 away from 1000, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 11:
350 goes into 3000 8 times with a remainder of 200.
Record the quotient 8 as the next digit in the result. 
Result so far: 43395.028
The remainder is 200 after subtracting 2800 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 12:
350 goes into 2000 5 times with a remainder of 250.
Record the quotient 5 as the next digit in the result. 
Result so far: 43395.0285
Deduct 1750 from 2000 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 13:
350 can be fit into 2500 7 times, resulting in a remainder of 50.
The next digit of our result is 7. 
Result so far: 43395.02857
Deduct 2450 from 2500 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 14:
350 can be fit into 500 1 times, resulting in a remainder of 150.
Put 1 as the next digit of the answer. 
Result so far: 43395.028571
If we subtract 350 from 500, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 15:
If we divide 1500 by 350, we get 4 and a remainder of 100.
Use 4 as the next digit of our solution. 
Result so far: 43395.0285714
If we take 1400 away from 1500, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 16:
350 goes into 1000 2 times with a remainder of 300.
The next digit of our result is 2. 
Result so far: 43395.02857142
Subtract 700 from 1000 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The quotient of the division is 43395.02857142, and the remainder is 3e-07.
