We divide 39905596 by 661
We want to divide 39905596 by 661.

Let's proceed to step 1:
When dividing 3 by 661, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 661

Step 2:
When dividing 39 by 661, we get 0 with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 661

Step 3:
661 can be fit into 399 0 times, resulting in a remainder of 399.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 399 to get 399.
Append the next digit (0) from the dividend to 399 and continue with: 3990 / 661

Let's proceed to step 4:
3990 divided by 661 is 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 24 after subtracting 3966 from 3990.
Include the next digit (5) from the dividend after 24, then repeat: 245 / 661

Advancing to step 5:
The number 661 fits into 245 0 times, leaving a remainder of 245.
Write down 0 as next digit of the result. 
Result so far: 60.0
Deduct 0 from 245 and we're left with 245.
Take the next digit (5) from the dividend and append it to 245, then repeat: 2455 / 661

Step 6:
2455 divided by 661 is 3 with a remainder of 472.
Record the quotient 3 as the next digit in the result. 
Result so far: 603.0
If we subtract 1983 from 2455, we get 472.
Include the next digit (9) from the dividend after 472, then repeat: 4729 / 661

Let's proceed to step 7:
661 goes into 4729 7 times with a remainder of 102.
Record the quotient 7 as the next digit in the result. 
Result so far: 6037.0
Deduct 4627 from 4729 and we're left with 102.
Bring next digit (6) of the dividend behind the 102 and repeat the process: 1026 / 661

Let's proceed to step 8:
1026 divided by 661 is 1 with a remainder of 365.
Put 1 as the next digit of the answer. 
Result so far: 60371.0
Deduct 661 from 1026 and we're left with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Moving on to step 9:
661 can be fit into 3650 5 times, resulting in a remainder of 345.
The next digit of our result is 5. 
Result so far: 60371.5
Subtracting 3305 from 3650 leaves us with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Moving on to step 10:
If we divide 3450 by 661, we get 5 and a remainder of 145.
Use 5 as the next digit of our solution. 
Result so far: 60371.55
The remainder is 145 after subtracting 3305 from 3450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

The final outcome is 60371.55, with a leftover of 0.145.
