We're dividing 12958783 by 753 
We want to figure out the number of times 12958783 can be divided by 753.

Going ahead to step 1:
When dividing 1 by 753, we get 0 with 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.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 753

Step 2:
When dividing 12 by 753, we get 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 753

Moving on to step 3:
If we divide 129 by 753, we get 0 and a remainder of 129.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 129, we end up with 129.
Bring next digit (5) of the dividend behind the 129 and repeat the process: 1295 / 753

On to step 4:
The number 753 fits into 1295 1 times, leaving a remainder of 542.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 753 from 1295 to get 542.
Append the next digit (8) from the dividend to 542 and continue with: 5428 / 753

Step 5:
753 goes into 5428 7 times with a remainder of 157.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Deduct 5271 from 5428 and we're left with 157.
Include the next digit (7) from the dividend after 157, then repeat: 1577 / 753

Moving on to step 6:
The number 753 fits into 1577 2 times, leaving a remainder of 71.
Put 2 as the next digit of the answer. 
Result so far: 172.0
Subtracting 1506 from 1577 leaves us with 71.
Grab the next digit (8) from the dividend, add it to 71, then carry on: 718 / 753

Advancing to step 7:
When dividing 718 by 753, we get 0 with a remainder of 718.
Put 0 as the next digit of the answer. 
Result so far: 1720.0
Deduct 0 from 718 and we're left with 718.
Fetch the next digit (3) from the dividend, attach it to 718 and continue: 7183 / 753

Going ahead to step 8:
753 can be fit into 7183 9 times, resulting in a remainder of 406.
Use 9 as the next digit of our solution. 
Result so far: 17209.0
Subtract 6777 from 7183 to get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Moving on to step 9:
When dividing 4060 by 753, we get 5 with a remainder of 295.
The number 5 becomes the next digit in our result. 
Result so far: 17209.5
Subtracting 3765 from 4060 leaves us with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

On to step 10:
If we divide 2950 by 753, we get 3 and a remainder of 691.
Use 3 as the next digit of our solution. 
Result so far: 17209.53
Subtract 2259 from 2950 to get 691.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6910, and continue the process.

Let's proceed to step 11:
753 goes into 6910 9 times with a remainder of 133.
The next digit of our result is 9. 
Result so far: 17209.539
If we subtract 6777 from 6910, we get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Moving on to step 12:
If we divide 1330 by 753, we get 1 and a remainder of 577.
The number 1 becomes the next digit in our result. 
Result so far: 17209.5391
Subtracting 753 from 1330 leaves us with 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

Let's proceed to step 13:
The number 753 fits into 5770 7 times, leaving a remainder of 499.
Record the quotient 7 as the next digit in the result. 
Result so far: 17209.53917
If we take 5271 away from 5770, we end up with 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

Step 14:
4990 divided by 753 is 6 with a remainder of 472.
Use 6 as the next digit of our solution. 
Result so far: 17209.539176
If we take 4518 away from 4990, we end up with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Let's proceed to step 15:
4720 divided by 753 is 6 with a remainder of 202.
The next digit of our result is 6. 
Result so far: 17209.5391766
Deduct 4518 from 4720 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

The quotient of the division is 17209.5391766, and the remainder is 2.02e-06.
