Let's divide 18646229 by 377
We're looking to find how many times 377 goes into 18646229.

Going ahead to step 1:
377 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 377

Advancing to step 2:
377 can be fit into 18 0 times, resulting in a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Grab the next digit (6) from the dividend, add it to 18, then carry on: 186 / 377

Going ahead to step 3:
When dividing 186 by 377, we get 0 with a remainder of 186.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 186 to get 186.
Grab the next digit (4) from the dividend, add it to 186, then carry on: 1864 / 377

Advancing to step 4:
When dividing 1864 by 377, we get 4 with a remainder of 356.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 1508 from 1864, we get 356.
Fetch the next digit (6) from the dividend, attach it to 356 and continue: 3566 / 377

Let's proceed to step 5:
377 goes into 3566 9 times with a remainder of 173.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
Subtract 3393 from 3566 to get 173.
Bring next digit (2) of the dividend behind the 173 and repeat the process: 1732 / 377

Advancing to step 6:
If we divide 1732 by 377, we get 4 and a remainder of 224.
Record the quotient 4 as the next digit in the result. 
Result so far: 494.0
If we subtract 1508 from 1732, we get 224.
Include the next digit (2) from the dividend after 224, then repeat: 2242 / 377

On to step 7:
2242 divided by 377 is 5 with a remainder of 357.
The next digit of our result is 5. 
Result so far: 4945.0
Subtracting 1885 from 2242 leaves us with 357.
Take the next digit (9) from the dividend and append it to 357, then repeat: 3579 / 377

Step 8:
The number 377 fits into 3579 9 times, leaving a remainder of 186.
The next digit of our result is 9. 
Result so far: 49459.0
The remainder is 186 after subtracting 3393 from 3579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 9:
When dividing 1860 by 377, we get 4 with a remainder of 352.
Use 4 as the next digit of our solution. 
Result so far: 49459.4
Deduct 1508 from 1860 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 10:
If we divide 3520 by 377, we get 9 and a remainder of 127.
Write down 9 as next digit of the result. 
Result so far: 49459.49
The remainder is 127 after subtracting 3393 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Moving on to step 11:
When dividing 1270 by 377, we get 3 with a remainder of 139.
Record the quotient 3 as the next digit in the result. 
Result so far: 49459.493
Deduct 1131 from 1270 and we're left with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Advancing to step 12:
When dividing 1390 by 377, we get 3 with a remainder of 259.
Put 3 as the next digit of the answer. 
Result so far: 49459.4933
Subtract 1131 from 1390 to get 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

The final outcome is 49459.4933, with a leftover of 0.00259.
