We look at the division of 17210926 by 253 
We want to figure out the number of times 17210926 can be divided by 253.

Going ahead to step 1:
253 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 253

Let's proceed to step 2:
If we divide 17 by 253, we get 0 and a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 253

Going ahead to step 3:
If we divide 172 by 253, we get 0 and a remainder of 172.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 172 after subtracting 0 from 172.
Bring next digit (1) of the dividend behind the 172 and repeat the process: 1721 / 253

Going ahead to step 4:
253 goes into 1721 6 times with a remainder of 203.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 1518 from 1721 leaves us with 203.
Grab the next digit (0) from the dividend, add it to 203, then carry on: 2030 / 253

On to step 5:
253 can be fit into 2030 8 times, resulting in a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
Deduct 2024 from 2030 and we're left with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 253

Step 6:
The number 253 fits into 69 0 times, leaving a remainder of 69.
The next digit of our result is 0. 
Result so far: 680.0
Deduct 0 from 69 and we're left with 69.
Grab the next digit (2) from the dividend, add it to 69, then carry on: 692 / 253

Going ahead to step 7:
If we divide 692 by 253, we get 2 and a remainder of 186.
Record the quotient 2 as the next digit in the result. 
Result so far: 6802.0
Subtract 506 from 692 to get 186.
Bring next digit (6) of the dividend behind the 186 and repeat the process: 1866 / 253

Advancing to step 8:
253 goes into 1866 7 times with a remainder of 95.
Use 7 as the next digit of our solution. 
Result so far: 68027.0
Deduct 1771 from 1866 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 9:
If we divide 950 by 253, we get 3 and a remainder of 191.
Use 3 as the next digit of our solution. 
Result so far: 68027.3
If we take 759 away from 950, we end up with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Step 10:
When dividing 1910 by 253, we get 7 with a remainder of 139.
Use 7 as the next digit of our solution. 
Result so far: 68027.37
Subtract 1771 from 1910 to get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

On to step 11:
253 can be fit into 1390 5 times, resulting in a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 68027.375
If we take 1265 away from 1390, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 12:
If we divide 1250 by 253, we get 4 and a remainder of 238.
Use 4 as the next digit of our solution. 
Result so far: 68027.3754
If we subtract 1012 from 1250, we get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 13:
2380 divided by 253 is 9 with a remainder of 103.
Record the quotient 9 as the next digit in the result. 
Result so far: 68027.37549
The remainder is 103 after subtracting 2277 from 2380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

On to step 14:
The number 253 fits into 1030 4 times, leaving a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 68027.375494
Subtract 1012 from 1030 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 15:
If we divide 180 by 253, we get 0 and a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 68027.375494
Subtracting 0 from 180 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 16:
253 goes into 1800 7 times with a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 68027.37549407
Deduct 1771 from 1800 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Our division results in 68027.37549407 with a remaining 2.9e-08.
