Subtracting 0 from 7 leaves us with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 986

Moving on to step 2:
986 goes into 72 0 times with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Fetch the next digit (0) from the dividend, attach it to 72 and continue: 720 / 986

Let's proceed to step 3:
986 can be fit into 720 0 times, resulting in a remainder of 720.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 720 and we're left with 720.
Append the next digit (3) from the dividend to 720 and continue with: 7203 / 986

Advancing to step 4:
When dividing 7203 by 986, we get 7 with a remainder of 301.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 6902 from 7203 and we're left with 301.
Fetch the next digit (6) from the dividend, attach it to 301 and continue: 3016 / 986

Step 5:
3016 divided by 986 is 3 with a remainder of 58.
Put 3 as the next digit of the answer. 
Result so far: 73.0
Subtract 2958 from 3016 to get 58.
Include the next digit (6) from the dividend after 58, then repeat: 586 / 986

Going ahead to step 6:
586 divided by 986 is 0 with a remainder of 586.
Record the quotient 0 as the next digit in the result. 
Result so far: 730.0
Subtract 0 from 586 to get 586.
Bring next digit (7) of the dividend behind the 586 and repeat the process: 5867 / 986

Moving on to step 7:
986 goes into 5867 5 times with a remainder of 937.
The number 5 becomes the next digit in our result. 
Result so far: 7305.0
The remainder is 937 after subtracting 4930 from 5867.
Include the next digit (3) from the dividend after 937, then repeat: 9373 / 986

Advancing to step 8:
When dividing 9373 by 986, we get 9 with a remainder of 499.
Use 9 as the next digit of our solution. 
Result so far: 73059.0
If we take 8874 away from 9373, we end up with 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

On to step 9:
The number 986 fits into 4990 5 times, leaving a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 73059.5
The remainder is 60 after subtracting 4930 from 4990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
986 can be fit into 600 0 times, resulting in a remainder of 600.
Write down 0 as next digit of the result. 
Result so far: 73059.5
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 11:
986 can be fit into 6000 6 times, resulting in a remainder of 84.
The next digit of our result is 6. 
Result so far: 73059.506
Subtracting 5916 from 6000 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 12:
The number 986 fits into 840 0 times, leaving a remainder of 840.
The next digit of our result is 0. 
Result so far: 73059.506
Subtracting 0 from 840 leaves us with 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Advancing to step 13:
8400 divided by 986 is 8 with a remainder of 512.
Put 8 as the next digit of the answer. 
Result so far: 73059.50608
The remainder is 512 after subtracting 7888 from 8400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Let's proceed to step 14:
The number 986 fits into 5120 5 times, leaving a remainder of 190.
Record the quotient 5 as the next digit in the result. 
Result so far: 73059.506085
Deduct 4930 from 5120 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.

On to step 15:
If we divide 1900 by 986, we get 1 and a remainder of 914.
The next digit of our result is 1. 
Result so far: 73059.5060851
The remainder is 914 after subtracting 986 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9140, and continue the process.

Let's proceed to step 16:
986 can be fit into 9140 9 times, resulting in a remainder of 266.
Use 9 as the next digit of our solution. 
Result so far: 73059.50608519
Subtract 8874 from 9140 to get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

The final outcome is 73059.50608519, with a leftover of 2.66e-07.
