We're dividing 73093351 by 406 
Our goal is to divide 73093351 by 406.

Moving on to step 1:
406 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
Deduct 0 from 7 and we're left with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 406

Going ahead to step 2:
When dividing 73 by 406, we get 0 with a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Fetch the next digit (0) from the dividend, attach it to 73 and continue: 730 / 406

Let's proceed to step 3:
406 can be fit into 730 1 times, resulting in a remainder of 324.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 406 from 730 to get 324.
Fetch the next digit (9) from the dividend, attach it to 324 and continue: 3249 / 406

Advancing to step 4:
When dividing 3249 by 406, we get 8 with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtract 3248 from 3249 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 406

Moving on to step 5:
406 can be fit into 13 0 times, resulting in a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 180.0
Subtracting 0 from 13 leaves us with 13.
Bring next digit (3) of the dividend behind the 13 and repeat the process: 133 / 406

Advancing to step 6:
406 goes into 133 0 times with a remainder of 133.
Write down 0 as next digit of the result. 
Result so far: 1800.0
Deduct 0 from 133 and we're left with 133.
Include the next digit (5) from the dividend after 133, then repeat: 1335 / 406

On to step 7:
406 can be fit into 1335 3 times, resulting in a remainder of 117.
Record the quotient 3 as the next digit in the result. 
Result so far: 18003.0
Deduct 1218 from 1335 and we're left with 117.
Include the next digit (1) from the dividend after 117, then repeat: 1171 / 406

Advancing to step 8:
406 can be fit into 1171 2 times, resulting in a remainder of 359.
The next digit of our result is 2. 
Result so far: 180032.0
If we take 812 away from 1171, we end up with 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Advancing to step 9:
If we divide 3590 by 406, we get 8 and a remainder of 342.
Put 8 as the next digit of the answer. 
Result so far: 180032.8
Subtract 3248 from 3590 to get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Step 10:
The number 406 fits into 3420 8 times, leaving a remainder of 172.
Record the quotient 8 as the next digit in the result. 
Result so far: 180032.88
Subtracting 3248 from 3420 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

The final outcome is 180032.88, with a leftover of 0.172.
