Let's divide 45690309 by 60
We want to divide 45690309 by 60.

Going ahead to step 1:
4 divided by 60 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 60

Step 2:
If we divide 45 by 60, we get 0 and a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Include the next digit (6) from the dividend after 45, then repeat: 456 / 60

Moving on to step 3:
456 divided by 60 is 7 with a remainder of 36.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 420 from 456 to get 36.
Bring next digit (9) of the dividend behind the 36 and repeat the process: 369 / 60

On to step 4:
The number 60 fits into 369 6 times, leaving a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 76.0
Subtract 360 from 369 to get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 60

Going ahead to step 5:
If we divide 90 by 60, we get 1 and a remainder of 30.
The next digit of our result is 1. 
Result so far: 761.0
Subtracting 60 from 90 leaves us with 30.
Include the next digit (3) from the dividend after 30, then repeat: 303 / 60

Moving on to step 6:
If we divide 303 by 60, we get 5 and a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 7615.0
If we take 300 away from 303, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 60

Going ahead to step 7:
60 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 76150.0
The remainder is 30 after subtracting 0 from 30.
Append the next digit (9) from the dividend to 30 and continue with: 309 / 60

On to step 8:
60 goes into 309 5 times with a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 761505.0
If we take 300 away from 309, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
60 can be fit into 90 1 times, resulting in a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 761505.1
Subtracting 60 from 90 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
If we divide 300 by 60, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 761505.15
If we take 300 away from 300, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
60 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 761505.15
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 12:
If we divide 0 by 60, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 761505.15
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 761505.15 with a remainder of 0.0.
