We look at the division of 51521003 by 298 
Our goal is to divide 51521003 by 298.

Step 1:
When dividing 5 by 298, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 298

Moving on to step 2:
If we divide 51 by 298, we get 0 and a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Include the next digit (5) from the dividend after 51, then repeat: 515 / 298

Step 3:
When dividing 515 by 298, we get 1 with a remainder of 217.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 298 from 515 and we're left with 217.
Fetch the next digit (2) from the dividend, attach it to 217 and continue: 2172 / 298

Moving on to step 4:
When dividing 2172 by 298, we get 7 with a remainder of 86.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 2086 from 2172, we get 86.
Bring next digit (1) of the dividend behind the 86 and repeat the process: 861 / 298

Advancing to step 5:
298 can be fit into 861 2 times, resulting in a remainder of 265.
Record the quotient 2 as the next digit in the result. 
Result so far: 172.0
The remainder is 265 after subtracting 596 from 861.
Grab the next digit (0) from the dividend, add it to 265, then carry on: 2650 / 298

Moving on to step 6:
The number 298 fits into 2650 8 times, leaving a remainder of 266.
Use 8 as the next digit of our solution. 
Result so far: 1728.0
Subtract 2384 from 2650 to get 266.
Take the next digit (0) from the dividend and append it to 266, then repeat: 2660 / 298

Let's proceed to step 7:
The number 298 fits into 2660 8 times, leaving a remainder of 276.
Put 8 as the next digit of the answer. 
Result so far: 17288.0
If we subtract 2384 from 2660, we get 276.
Fetch the next digit (3) from the dividend, attach it to 276 and continue: 2763 / 298

Let's proceed to step 8:
When dividing 2763 by 298, we get 9 with a remainder of 81.
Put 9 as the next digit of the answer. 
Result so far: 172889.0
Subtracting 2682 from 2763 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 9:
When dividing 810 by 298, we get 2 with a remainder of 214.
Write down 2 as next digit of the result. 
Result so far: 172889.2
If we subtract 596 from 810, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

On to step 10:
When dividing 2140 by 298, we get 7 with a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 172889.27
If we subtract 2086 from 2140, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 11:
298 can be fit into 540 1 times, resulting in a remainder of 242.
Record the quotient 1 as the next digit in the result. 
Result so far: 172889.271
If we take 298 away from 540, we end up with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Step 12:
2420 divided by 298 is 8 with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 172889.2718
Deduct 2384 from 2420 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 13:
The number 298 fits into 360 1 times, leaving a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 172889.27181
If we subtract 298 from 360, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 14:
298 can be fit into 620 2 times, resulting in a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 172889.271812
If we subtract 596 from 620, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 15:
When dividing 240 by 298, we get 0 with a remainder of 240.
Put 0 as the next digit of the answer. 
Result so far: 172889.271812
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 16:
The number 298 fits into 2400 8 times, leaving a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 172889.27181208
Subtracting 2384 from 2400 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 172889.27181208, and the remainder is 1.6e-08.
