When dividing 9 by 610, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 610

Moving on to step 2:
If we divide 91 by 610, we get 0 and a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Bring next digit (7) of the dividend behind the 91 and repeat the process: 917 / 610

On to step 3:
917 divided by 610 is 1 with a remainder of 307.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 610 from 917 and we're left with 307.
Include the next digit (0) from the dividend after 307, then repeat: 3070 / 610

On to step 4:
When dividing 3070 by 610, we get 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 3050 from 3070 and we're left with 20.
Fetch the next digit (8) from the dividend, attach it to 20 and continue: 208 / 610

Moving on to step 5:
610 goes into 208 0 times with a remainder of 208.
The next digit of our result is 0. 
Result so far: 150.0
Subtracting 0 from 208 leaves us with 208.
Grab the next digit (1) from the dividend, add it to 208, then carry on: 2081 / 610

Going ahead to step 6:
2081 divided by 610 is 3 with a remainder of 251.
Write down 3 as next digit of the result. 
Result so far: 1503.0
Subtracting 1830 from 2081 leaves us with 251.
Append the next digit (8) from the dividend to 251 and continue with: 2518 / 610

Moving on to step 7:
If we divide 2518 by 610, we get 4 and a remainder of 78.
Use 4 as the next digit of our solution. 
Result so far: 15034.0
The remainder is 78 after subtracting 2440 from 2518.
Include the next digit (1) from the dividend after 78, then repeat: 781 / 610

Going ahead to step 8:
610 goes into 781 1 times with a remainder of 171.
Put 1 as the next digit of the answer. 
Result so far: 150341.0
The remainder is 171 after subtracting 610 from 781.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Going ahead to step 9:
The number 610 fits into 1710 2 times, leaving a remainder of 490.
Put 2 as the next digit of the answer. 
Result so far: 150341.2
The remainder is 490 after subtracting 1220 from 1710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Moving on to step 10:
The number 610 fits into 4900 8 times, leaving a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 150341.28
The remainder is 20 after subtracting 4880 from 4900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
200 divided by 610 is 0 with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 150341.28
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 12:
If we divide 2000 by 610, we get 3 and a remainder of 170.
Record the quotient 3 as the next digit in the result. 
Result so far: 150341.2803
Subtracting 1830 from 2000 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 13:
1700 divided by 610 is 2 with a remainder of 480.
The number 2 becomes the next digit in our result. 
Result so far: 150341.28032
Subtract 1220 from 1700 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 14:
When dividing 4800 by 610, we get 7 with a remainder of 530.
Put 7 as the next digit of the answer. 
Result so far: 150341.280327
If we take 4270 away from 4800, we end up with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Advancing to step 15:
5300 divided by 610 is 8 with a remainder of 420.
The number 8 becomes the next digit in our result. 
Result so far: 150341.2803278
Subtract 4880 from 5300 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 16:
The number 610 fits into 4200 6 times, leaving a remainder of 540.
Put 6 as the next digit of the answer. 
Result so far: 150341.28032786
Subtracting 3660 from 4200 leaves us with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

The quotient of the division is 150341.28032786, and the remainder is 5.4e-07.
