We look at the division of 1455021 by 351 
We're looking to find how many times 351 goes into 1455021.

On to step 1:
1 divided by 351 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 351

Going ahead to step 2:
14 divided by 351 is 0 with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Bring next digit (5) of the dividend behind the 14 and repeat the process: 145 / 351

Let's proceed to step 3:
351 can be fit into 145 0 times, resulting in a remainder of 145.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 145 after subtracting 0 from 145.
Append the next digit (5) from the dividend to 145 and continue with: 1455 / 351

Let's proceed to step 4:
If we divide 1455 by 351, we get 4 and a remainder of 51.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 1404 from 1455 and we're left with 51.
Bring next digit (0) of the dividend behind the 51 and repeat the process: 510 / 351

Going ahead to step 5:
510 divided by 351 is 1 with a remainder of 159.
Write down 1 as next digit of the result. 
Result so far: 41.0
If we take 351 away from 510, we end up with 159.
Grab the next digit (2) from the dividend, add it to 159, then carry on: 1592 / 351

Step 6:
When dividing 1592 by 351, we get 4 with a remainder of 188.
Put 4 as the next digit of the answer. 
Result so far: 414.0
The remainder is 188 after subtracting 1404 from 1592.
Include the next digit (1) from the dividend after 188, then repeat: 1881 / 351

Let's proceed to step 7:
351 goes into 1881 5 times with a remainder of 126.
The next digit of our result is 5. 
Result so far: 4145.0
Deduct 1755 from 1881 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 8:
351 can be fit into 1260 3 times, resulting in a remainder of 207.
The next digit of our result is 3. 
Result so far: 4145.3
Subtracting 1053 from 1260 leaves us with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

On to step 9:
351 goes into 2070 5 times with a remainder of 315.
Put 5 as the next digit of the answer. 
Result so far: 4145.35
The remainder is 315 after subtracting 1755 from 2070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

On to step 10:
351 goes into 3150 8 times with a remainder of 342.
Use 8 as the next digit of our solution. 
Result so far: 4145.358
Subtracting 2808 from 3150 leaves us with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Going ahead to step 11:
351 goes into 3420 9 times with a remainder of 261.
Record the quotient 9 as the next digit in the result. 
Result so far: 4145.3589
If we subtract 3159 from 3420, we get 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Let's proceed to step 12:
351 goes into 2610 7 times with a remainder of 153.
Use 7 as the next digit of our solution. 
Result so far: 4145.35897
If we subtract 2457 from 2610, we get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Advancing to step 13:
If we divide 1530 by 351, we get 4 and a remainder of 126.
Use 4 as the next digit of our solution. 
Result so far: 4145.358974
Subtract 1404 from 1530 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 14:
351 can be fit into 1260 3 times, resulting in a remainder of 207.
Put 3 as the next digit of the answer. 
Result so far: 4145.3589743
If we subtract 1053 from 1260, we get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

On to step 15:
If we divide 2070 by 351, we get 5 and a remainder of 315.
Use 5 as the next digit of our solution. 
Result so far: 4145.35897435
Subtract 1755 from 2070 to get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

The final result is 4145.35897435 with a remainder of 3.15e-07.
