Include the next digit (1) from the dividend after 252, then repeat: 2521 / 613

Going ahead to step 4:
The number 613 fits into 2521 4 times, leaving a remainder of 69.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 69 after subtracting 2452 from 2521.
Append the next digit (5) from the dividend to 69 and continue with: 695 / 613

Going ahead to step 5:
The number 613 fits into 695 1 times, leaving a remainder of 82.
Write down 1 as next digit of the result. 
Result so far: 41.0
Subtracting 613 from 695 leaves us with 82.
Append the next digit (0) from the dividend to 82 and continue with: 820 / 613

Let's proceed to step 6:
If we divide 820 by 613, we get 1 and a remainder of 207.
Write down 1 as next digit of the result. 
Result so far: 411.0
If we take 613 away from 820, we end up with 207.
Take the next digit (3) from the dividend and append it to 207, then repeat: 2073 / 613

Advancing to step 7:
The number 613 fits into 2073 3 times, leaving a remainder of 234.
Record the quotient 3 as the next digit in the result. 
Result so far: 4113.0
Subtracting 1839 from 2073 leaves us with 234.
Take the next digit (8) from the dividend and append it to 234, then repeat: 2348 / 613

Advancing to step 8:
613 can be fit into 2348 3 times, resulting in a remainder of 509.
Record the quotient 3 as the next digit in the result. 
Result so far: 41133.0
If we take 1839 away from 2348, we end up with 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Advancing to step 9:
5090 divided by 613 is 8 with a remainder of 186.
Put 8 as the next digit of the answer. 
Result so far: 41133.8
Subtracting 4904 from 5090 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Advancing to step 10:
613 goes into 1860 3 times with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 41133.83
Subtracting 1839 from 1860 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 11:
210 divided by 613 is 0 with a remainder of 210.
Write down 0 as next digit of the result. 
Result so far: 41133.83
If we take 0 away from 210, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 12:
If we divide 2100 by 613, we get 3 and a remainder of 261.
The next digit of our result is 3. 
Result so far: 41133.8303
If we subtract 1839 from 2100, 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.

Advancing to step 13:
When dividing 2610 by 613, we get 4 with a remainder of 158.
Use 4 as the next digit of our solution. 
Result so far: 41133.83034
Subtract 2452 from 2610 to get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 14:
1580 divided by 613 is 2 with a remainder of 354.
The number 2 becomes the next digit in our result. 
Result so far: 41133.830342
If we subtract 1226 from 1580, we get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Moving on to step 15:
613 can be fit into 3540 5 times, resulting in a remainder of 475.
Put 5 as the next digit of the answer. 
Result so far: 41133.8303425
The remainder is 475 after subtracting 3065 from 3540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Moving on to step 16:
When dividing 4750 by 613, we get 7 with a remainder of 459.
Record the quotient 7 as the next digit in the result. 
Result so far: 41133.83034257
If we take 4291 away from 4750, we end up with 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Our division results in 41133.83034257 with a remaining 4.59e-07.
