60409864 ÷ 377 
Let's see how many times 377 fits into 60409864.

On to step 1:
377 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 377

Advancing to step 2:
If we divide 60 by 377, we get 0 and a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 60 and we're left with 60.
Take the next digit (4) from the dividend and append it to 60, then repeat: 604 / 377

Going ahead to step 3:
377 can be fit into 604 1 times, resulting in a remainder of 227.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 227 after subtracting 377 from 604.
Bring next digit (0) of the dividend behind the 227 and repeat the process: 2270 / 377

Let's proceed to step 4:
2270 divided by 377 is 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we take 2262 away from 2270, we end up with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 377

Step 5:
If we divide 89 by 377, we get 0 and a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 160.0
Subtracting 0 from 89 leaves us with 89.
Grab the next digit (8) from the dividend, add it to 89, then carry on: 898 / 377

Step 6:
The number 377 fits into 898 2 times, leaving a remainder of 144.
The number 2 becomes the next digit in our result. 
Result so far: 1602.0
Deduct 754 from 898 and we're left with 144.
Append the next digit (6) from the dividend to 144 and continue with: 1446 / 377

Let's proceed to step 7:
If we divide 1446 by 377, we get 3 and a remainder of 315.
Write down 3 as next digit of the result. 
Result so far: 16023.0
Deduct 1131 from 1446 and we're left with 315.
Take the next digit (4) from the dividend and append it to 315, then repeat: 3154 / 377

Advancing to step 8:
3154 divided by 377 is 8 with a remainder of 138.
The number 8 becomes the next digit in our result. 
Result so far: 160238.0
If we subtract 3016 from 3154, we get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Moving on to step 9:
377 goes into 1380 3 times with a remainder of 249.
The number 3 becomes the next digit in our result. 
Result so far: 160238.3
If we subtract 1131 from 1380, we get 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Step 10:
377 goes into 2490 6 times with a remainder of 228.
Put 6 as the next digit of the answer. 
Result so far: 160238.36
Deduct 2262 from 2490 and we're left with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Moving on to step 11:
377 goes into 2280 6 times with a remainder of 18.
The next digit of our result is 6. 
Result so far: 160238.366
The remainder is 18 after subtracting 2262 from 2280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 160238.366, with a leftover of 0.0018.
