We divide 80365901 by 542
We're looking to find how many times 542 goes into 80365901.

On to step 1:
The number 542 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 542

Let's proceed to step 2:
542 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Bring next digit (3) of the dividend behind the 80 and repeat the process: 803 / 542

Advancing to step 3:
542 can be fit into 803 1 times, resulting in a remainder of 261.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 542 from 803 leaves us with 261.
Grab the next digit (6) from the dividend, add it to 261, then carry on: 2616 / 542

Let's proceed to step 4:
542 goes into 2616 4 times with a remainder of 448.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 2168 from 2616 leaves us with 448.
Include the next digit (5) from the dividend after 448, then repeat: 4485 / 542

Advancing to step 5:
When dividing 4485 by 542, we get 8 with a remainder of 149.
The number 8 becomes the next digit in our result. 
Result so far: 148.0
If we subtract 4336 from 4485, we get 149.
Take the next digit (9) from the dividend and append it to 149, then repeat: 1499 / 542

Moving on to step 6:
If we divide 1499 by 542, we get 2 and a remainder of 415.
The number 2 becomes the next digit in our result. 
Result so far: 1482.0
The remainder is 415 after subtracting 1084 from 1499.
Bring next digit (0) of the dividend behind the 415 and repeat the process: 4150 / 542

Going ahead to step 7:
542 goes into 4150 7 times with a remainder of 356.
The number 7 becomes the next digit in our result. 
Result so far: 14827.0
The remainder is 356 after subtracting 3794 from 4150.
Fetch the next digit (1) from the dividend, attach it to 356 and continue: 3561 / 542

Going ahead to step 8:
542 can be fit into 3561 6 times, resulting in a remainder of 309.
The next digit of our result is 6. 
Result so far: 148276.0
If we take 3252 away from 3561, we end up with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

On to step 9:
The number 542 fits into 3090 5 times, leaving a remainder of 380.
Record the quotient 5 as the next digit in the result. 
Result so far: 148276.5
Deduct 2710 from 3090 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 10:
The number 542 fits into 3800 7 times, leaving a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 148276.57
Subtracting 3794 from 3800 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
60 divided by 542 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 148276.57
The remainder is 60 after subtracting 0 from 60.
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 12:
The number 542 fits into 600 1 times, leaving a remainder of 58.
Use 1 as the next digit of our solution. 
Result so far: 148276.5701
Subtract 542 from 600 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 13:
580 divided by 542 is 1 with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 148276.57011
Subtracting 542 from 580 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final outcome is 148276.57011, with a leftover of 3.8e-05.
