We look at the division of 73591558 by 602 
Let's see how many times 602 fits into 73591558.

Moving on to step 1:
602 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 602

Step 2:
When dividing 73 by 602, we get 0 with a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Include the next digit (5) from the dividend after 73, then repeat: 735 / 602

Going ahead to step 3:
602 goes into 735 1 times with a remainder of 133.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 602 from 735, we get 133.
Include the next digit (9) from the dividend after 133, then repeat: 1339 / 602

Advancing to step 4:
If we divide 1339 by 602, we get 2 and a remainder of 135.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 1204 from 1339, we get 135.
Bring next digit (1) of the dividend behind the 135 and repeat the process: 1351 / 602

On to step 5:
602 goes into 1351 2 times with a remainder of 147.
Record the quotient 2 as the next digit in the result. 
Result so far: 122.0
Deduct 1204 from 1351 and we're left with 147.
Take the next digit (5) from the dividend and append it to 147, then repeat: 1475 / 602

On to step 6:
When dividing 1475 by 602, we get 2 with a remainder of 271.
Write down 2 as next digit of the result. 
Result so far: 1222.0
Deduct 1204 from 1475 and we're left with 271.
Include the next digit (5) from the dividend after 271, then repeat: 2715 / 602

Going ahead to step 7:
602 goes into 2715 4 times with a remainder of 307.
The number 4 becomes the next digit in our result. 
Result so far: 12224.0
Subtracting 2408 from 2715 leaves us with 307.
Append the next digit (8) from the dividend to 307 and continue with: 3078 / 602

Going ahead to step 8:
The number 602 fits into 3078 5 times, leaving a remainder of 68.
Put 5 as the next digit of the answer. 
Result so far: 122245.0
If we subtract 3010 from 3078, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 9:
602 can be fit into 680 1 times, resulting in a remainder of 78.
Write down 1 as next digit of the result. 
Result so far: 122245.1
Subtracting 602 from 680 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 10:
780 divided by 602 is 1 with a remainder of 178.
The number 1 becomes the next digit in our result. 
Result so far: 122245.11
If we take 602 away from 780, we end up with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

After the division, we end up with 122245.11 and a remainder of 0.178.
