661851 divided by 60 
Our goal is to divide 661851 by 60.

Going ahead to step 1:
If we divide 6 by 60, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 60

Step 2:
The number 60 fits into 66 1 times, leaving a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 60 from 66 to get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 60

Let's proceed to step 3:
The number 60 fits into 61 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 60 from 61 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 60

Advancing to step 4:
The number 60 fits into 18 0 times, leaving a remainder of 18.
The next digit of our result is 0. 
Result so far: 110.0
The remainder is 18 after subtracting 0 from 18.
Include the next digit (5) from the dividend after 18, then repeat: 185 / 60

Step 5:
The number 60 fits into 185 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 1103.0
If we take 180 away from 185, we end up with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 60

On to step 6:
51 divided by 60 is 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 11030.0
If we take 0 away from 51, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 7:
If we divide 510 by 60, we get 8 and a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 11030.8
If we take 480 away from 510, we end up 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.

Moving on to step 8:
60 can be fit into 300 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 11030.85
Deduct 300 from 300 and we're left 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 9:
60 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11030.85
Deduct 0 from 0 and we're left 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 10:
The number 60 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11030.85
If we take 0 away from 0, 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.

The final result is 11030.85 with a remainder of 0.0.
