If we take 2238 away from 2451, we end up with 213.
Append the next digit (3) from the dividend to 213 and continue with: 2133 / 373

Advancing to step 5:
2133 divided by 373 is 5 with a remainder of 268.
Write down 5 as next digit of the result. 
Result so far: 165.0
The remainder is 268 after subtracting 1865 from 2133.
Grab the next digit (5) from the dividend, add it to 268, then carry on: 2685 / 373

Moving on to step 6:
When dividing 2685 by 373, we get 7 with a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 1657.0
If we take 2611 away from 2685, we end up with 74.
Include the next digit (1) from the dividend after 74, then repeat: 741 / 373

Moving on to step 7:
373 can be fit into 741 1 times, resulting in a remainder of 368.
Record the quotient 1 as the next digit in the result. 
Result so far: 16571.0
Subtracting 373 from 741 leaves us with 368.
Append the next digit (0) from the dividend to 368 and continue with: 3680 / 373

Advancing to step 8:
When dividing 3680 by 373, we get 9 with a remainder of 323.
The number 9 becomes the next digit in our result. 
Result so far: 165719.0
Deduct 3357 from 3680 and we're left with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Going ahead to step 9:
If we divide 3230 by 373, we get 8 and a remainder of 246.
Put 8 as the next digit of the answer. 
Result so far: 165719.8
Subtracting 2984 from 3230 leaves us with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Advancing to step 10:
The number 373 fits into 2460 6 times, leaving a remainder of 222.
Put 6 as the next digit of the answer. 
Result so far: 165719.86
If we take 2238 away from 2460, we end up 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.

Let's proceed to step 11:
If we divide 2220 by 373, we get 5 and a remainder of 355.
The next digit of our result is 5. 
Result so far: 165719.865
If we take 1865 away from 2220, we end up with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Let's proceed to step 12:
The number 373 fits into 3550 9 times, leaving a remainder of 193.
Record the quotient 9 as the next digit in the result. 
Result so far: 165719.8659
If we take 3357 away from 3550, we end up with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Step 13:
373 goes into 1930 5 times with a remainder of 65.
The next digit of our result is 5. 
Result so far: 165719.86595
Subtracting 1865 from 1930 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 14:
If we divide 650 by 373, we get 1 and a remainder of 277.
Write down 1 as next digit of the result. 
Result so far: 165719.865951
Subtracting 373 from 650 leaves us with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Let's proceed to step 15:
2770 divided by 373 is 7 with a remainder of 159.
The next digit of our result is 7. 
Result so far: 165719.8659517
Deduct 2611 from 2770 and we're left with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Step 16:
373 goes into 1590 4 times with a remainder of 98.
The next digit of our result is 4. 
Result so far: 165719.86595174
Deduct 1492 from 1590 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

The final outcome is 165719.86595174, with a leftover of 9.8e-08.
