If we divide 9 by 653, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 653

Step 2:
653 can be fit into 90 0 times, resulting in a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Include the next digit (6) from the dividend after 90, then repeat: 906 / 653

Step 3:
653 can be fit into 906 1 times, resulting in a remainder of 253.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 653 from 906 and we're left with 253.
Bring next digit (8) of the dividend behind the 253 and repeat the process: 2538 / 653

On to step 4:
2538 divided by 653 is 3 with a remainder of 579.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 579 after subtracting 1959 from 2538.
Grab the next digit (4) from the dividend, add it to 579, then carry on: 5794 / 653

Step 5:
The number 653 fits into 5794 8 times, leaving a remainder of 570.
Record the quotient 8 as the next digit in the result. 
Result so far: 138.0
If we subtract 5224 from 5794, we get 570.
Fetch the next digit (1) from the dividend, attach it to 570 and continue: 5701 / 653

Step 6:
When dividing 5701 by 653, we get 8 with a remainder of 477.
The next digit of our result is 8. 
Result so far: 1388.0
Deduct 5224 from 5701 and we're left with 477.
Take the next digit (5) from the dividend and append it to 477, then repeat: 4775 / 653

Step 7:
When dividing 4775 by 653, we get 7 with a remainder of 204.
Record the quotient 7 as the next digit in the result. 
Result so far: 13887.0
Subtracting 4571 from 4775 leaves us with 204.
Fetch the next digit (4) from the dividend, attach it to 204 and continue: 2044 / 653

Moving on to step 8:
When dividing 2044 by 653, we get 3 with a remainder of 85.
Record the quotient 3 as the next digit in the result. 
Result so far: 138873.0
If we subtract 1959 from 2044, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 9:
If we divide 850 by 653, we get 1 and a remainder of 197.
The number 1 becomes the next digit in our result. 
Result so far: 138873.1
The remainder is 197 after subtracting 653 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

On to step 10:
If we divide 1970 by 653, we get 3 and a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 138873.13
The remainder is 11 after subtracting 1959 from 1970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 11:
If we divide 110 by 653, we get 0 and a remainder of 110.
Put 0 as the next digit of the answer. 
Result so far: 138873.13
Deduct 0 from 110 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 12:
1100 divided by 653 is 1 with a remainder of 447.
Write down 1 as next digit of the result. 
Result so far: 138873.1301
Subtracting 653 from 1100 leaves us with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Moving on to step 13:
653 goes into 4470 6 times with a remainder of 552.
Put 6 as the next digit of the answer. 
Result so far: 138873.13016
Subtract 3918 from 4470 to get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Let's proceed to step 14:
5520 divided by 653 is 8 with a remainder of 296.
Put 8 as the next digit of the answer. 
Result so far: 138873.130168
If we subtract 5224 from 5520, we get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 15:
If we divide 2960 by 653, we get 4 and a remainder of 348.
Use 4 as the next digit of our solution. 
Result so far: 138873.1301684
Subtract 2612 from 2960 to get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 16:
653 goes into 3480 5 times with a remainder of 215.
Write down 5 as next digit of the result. 
Result so far: 138873.13016845
Subtracting 3265 from 3480 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

In conclusion, the division gives 138873.13016845 with a balance of 2.15e-07.
