Advancing to step 5:
3485 divided by 610 is 5 with a remainder of 435.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
The remainder is 435 after subtracting 3050 from 3485.
Grab the next digit (8) from the dividend, add it to 435, then carry on: 4358 / 610

Advancing to step 6:
When dividing 4358 by 610, we get 7 with a remainder of 88.
Write down 7 as next digit of the result. 
Result so far: 357.0
Deduct 4270 from 4358 and we're left with 88.
Include the next digit (5) from the dividend after 88, then repeat: 885 / 610

On to step 7:
If we divide 885 by 610, we get 1 and a remainder of 275.
Put 1 as the next digit of the answer. 
Result so far: 3571.0
Subtracting 610 from 885 leaves us with 275.
Take the next digit (7) from the dividend and append it to 275, then repeat: 2757 / 610

Let's proceed to step 8:
610 goes into 2757 4 times with a remainder of 317.
Use 4 as the next digit of our solution. 
Result so far: 35714.0
Deduct 2440 from 2757 and we're left with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Step 9:
If we divide 3170 by 610, we get 5 and a remainder of 120.
Put 5 as the next digit of the answer. 
Result so far: 35714.5
Subtracting 3050 from 3170 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 10:
The number 610 fits into 1200 1 times, leaving a remainder of 590.
Record the quotient 1 as the next digit in the result. 
Result so far: 35714.51
Deduct 610 from 1200 and we're left with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Let's proceed to step 11:
When dividing 5900 by 610, we get 9 with a remainder of 410.
The number 9 becomes the next digit in our result. 
Result so far: 35714.519
Deduct 5490 from 5900 and we're left with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Moving on to step 12:
The number 610 fits into 4100 6 times, leaving a remainder of 440.
The number 6 becomes the next digit in our result. 
Result so far: 35714.5196
Subtract 3660 from 4100 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 13:
The number 610 fits into 4400 7 times, leaving a remainder of 130.
Put 7 as the next digit of the answer. 
Result so far: 35714.51967
If we take 4270 away from 4400, 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.

Moving on to step 14:
If we divide 1300 by 610, we get 2 and a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 35714.519672
If we subtract 1220 from 1300, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 15:
If we divide 800 by 610, we get 1 and a remainder of 190.
Use 1 as the next digit of our solution. 
Result so far: 35714.5196721
Deduct 610 from 800 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 16:
610 goes into 1900 3 times with a remainder of 70.
Use 3 as the next digit of our solution. 
Result so far: 35714.51967213
Subtracting 1830 from 1900 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The quotient of the division is 35714.51967213, and the remainder is 7e-08.
