373977 ÷ 42 
Our goal is to divide 373977 by 42.

Step 1:
42 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 42

On to step 2:
37 divided by 42 is 0 with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 37 after subtracting 0 from 37.
Fetch the next digit (3) from the dividend, attach it to 37 and continue: 373 / 42

Let's proceed to step 3:
42 goes into 373 8 times with a remainder of 37.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 37 after subtracting 336 from 373.
Grab the next digit (9) from the dividend, add it to 37, then carry on: 379 / 42

Step 4:
If we divide 379 by 42, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
If we subtract 378 from 379, we get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 42

Moving on to step 5:
When dividing 17 by 42, we get 0 with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 890.0
Deduct 0 from 17 and we're left with 17.
Bring next digit (7) of the dividend behind the 17 and repeat the process: 177 / 42

Let's proceed to step 6:
If we divide 177 by 42, we get 4 and a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 8904.0
The remainder is 9 after subtracting 168 from 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
42 can be fit into 90 2 times, resulting in a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 8904.2
If we subtract 84 from 90, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
The number 42 fits into 60 1 times, leaving a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 8904.21
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
42 can be fit into 180 4 times, resulting in a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 8904.214
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
42 can be fit into 120 2 times, resulting in a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 8904.2142
Deduct 84 from 120 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 11:
42 goes into 360 8 times with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 8904.21428
If we take 336 away from 360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 12:
If we divide 240 by 42, we get 5 and a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 8904.214285
The remainder is 30 after subtracting 210 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 13:
42 goes into 300 7 times with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 8904.2142857
If we take 294 away from 300, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
When dividing 60 by 42, we get 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 8904.21428571
If we take 42 away from 60, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 8904.21428571 with a remaining 1.8e-08.
