We're dividing 53045239 by 351 
We want to figure out the number of times 53045239 can be divided by 351.

On to step 1:
The number 351 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 351

Step 2:
351 can be fit into 53 0 times, resulting in a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Append the next digit (0) from the dividend to 53 and continue with: 530 / 351

Moving on to step 3:
If we divide 530 by 351, we get 1 and a remainder of 179.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 351 from 530, we get 179.
Bring next digit (4) of the dividend behind the 179 and repeat the process: 1794 / 351

On to step 4:
351 can be fit into 1794 5 times, resulting in a remainder of 39.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 1755 from 1794 to get 39.
Include the next digit (5) from the dividend after 39, then repeat: 395 / 351

Step 5:
351 can be fit into 395 1 times, resulting in a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 151.0
If we subtract 351 from 395, we get 44.
Take the next digit (2) from the dividend and append it to 44, then repeat: 442 / 351

Advancing to step 6:
The number 351 fits into 442 1 times, leaving a remainder of 91.
The number 1 becomes the next digit in our result. 
Result so far: 1511.0
Subtract 351 from 442 to get 91.
Grab the next digit (3) from the dividend, add it to 91, then carry on: 913 / 351

Going ahead to step 7:
The number 351 fits into 913 2 times, leaving a remainder of 211.
Use 2 as the next digit of our solution. 
Result so far: 15112.0
If we take 702 away from 913, we end up with 211.
Include the next digit (9) from the dividend after 211, then repeat: 2119 / 351

Let's proceed to step 8:
351 can be fit into 2119 6 times, resulting in a remainder of 13.
The next digit of our result is 6. 
Result so far: 151126.0
The remainder is 13 after subtracting 2106 from 2119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 9:
When dividing 130 by 351, we get 0 with a remainder of 130.
Use 0 as the next digit of our solution. 
Result so far: 151126.0
If we take 0 away from 130, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 10:
1300 divided by 351 is 3 with a remainder of 247.
Record the quotient 3 as the next digit in the result. 
Result so far: 151126.03
If we subtract 1053 from 1300, we get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Let's proceed to step 11:
The number 351 fits into 2470 7 times, leaving a remainder of 13.
The next digit of our result is 7. 
Result so far: 151126.037
If we subtract 2457 from 2470, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 12:
When dividing 130 by 351, we get 0 with a remainder of 130.
The number 0 becomes the next digit in our result. 
Result so far: 151126.037
If we subtract 0 from 130, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 13:
When dividing 1300 by 351, we get 3 with a remainder of 247.
Write down 3 as next digit of the result. 
Result so far: 151126.03703
Deduct 1053 from 1300 and we're left with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Let's proceed to step 14:
If we divide 2470 by 351, we get 7 and a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 151126.037037
Subtracting 2457 from 2470 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 15:
When dividing 130 by 351, we get 0 with a remainder of 130.
The next digit of our result is 0. 
Result so far: 151126.037037
If we subtract 0 from 130, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 16:
The number 351 fits into 1300 3 times, leaving a remainder of 247.
Put 3 as the next digit of the answer. 
Result so far: 151126.03703703
If we subtract 1053 from 1300, we get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

After the division, we end up with 151126.03703703 and a remainder of 2.47e-07.
