We look at the division of 1223309 by 377 
We're looking to find how many times 377 goes into 1223309.

Moving on to step 1:
377 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 377

Going ahead to step 2:
If we divide 12 by 377, we get 0 and a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 377

Let's proceed to step 3:
377 can be fit into 122 0 times, resulting in a remainder of 122.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 122 to get 122.
Append the next digit (3) from the dividend to 122 and continue with: 1223 / 377

Moving on to step 4:
377 goes into 1223 3 times with a remainder of 92.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 1131 from 1223, we get 92.
Append the next digit (3) from the dividend to 92 and continue with: 923 / 377

Let's proceed to step 5:
If we divide 923 by 377, we get 2 and a remainder of 169.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
Deduct 754 from 923 and we're left with 169.
Bring next digit (0) of the dividend behind the 169 and repeat the process: 1690 / 377

On to step 6:
The number 377 fits into 1690 4 times, leaving a remainder of 182.
Record the quotient 4 as the next digit in the result. 
Result so far: 324.0
If we subtract 1508 from 1690, we get 182.
Take the next digit (9) from the dividend and append it to 182, then repeat: 1829 / 377

Step 7:
If we divide 1829 by 377, we get 4 and a remainder of 321.
The next digit of our result is 4. 
Result so far: 3244.0
The remainder is 321 after subtracting 1508 from 1829.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Let's proceed to step 8:
377 goes into 3210 8 times with a remainder of 194.
The next digit of our result is 8. 
Result so far: 3244.8
Deduct 3016 from 3210 and we're left with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Going ahead to step 9:
If we divide 1940 by 377, we get 5 and a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 3244.85
Subtracting 1885 from 1940 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 10:
377 can be fit into 550 1 times, resulting in a remainder of 173.
The next digit of our result is 1. 
Result so far: 3244.851
Subtract 377 from 550 to get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Step 11:
1730 divided by 377 is 4 with a remainder of 222.
The next digit of our result is 4. 
Result so far: 3244.8514
Deduct 1508 from 1730 and we're left with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Going ahead to step 12:
377 goes into 2220 5 times with a remainder of 335.
Use 5 as the next digit of our solution. 
Result so far: 3244.85145
If we subtract 1885 from 2220, we get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Going ahead to step 13:
If we divide 3350 by 377, we get 8 and a remainder of 334.
Record the quotient 8 as the next digit in the result. 
Result so far: 3244.851458
If we take 3016 away from 3350, we end up with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Moving on to step 14:
377 goes into 3340 8 times with a remainder of 324.
Put 8 as the next digit of the answer. 
Result so far: 3244.8514588
Subtracting 3016 from 3340 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

The final outcome is 3244.8514588, with a leftover of 3.24e-06.
