Let's divide 357923 by 42
We want to figure out the number of times 357923 can be divided by 42.

Moving on to step 1:
42 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 42

Step 2:
42 can be fit into 35 0 times, resulting in a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Grab the next digit (7) from the dividend, add it to 35, then carry on: 357 / 42

Advancing to step 3:
If we divide 357 by 42, we get 8 and a remainder of 21.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 336 from 357, we get 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 42

Moving on to step 4:
If we divide 219 by 42, we get 5 and a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
Subtracting 210 from 219 leaves us with 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 42

Advancing to step 5:
42 can be fit into 92 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 852.0
Subtract 84 from 92 to get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 42

Going ahead to step 6:
The number 42 fits into 83 1 times, leaving a remainder of 41.
Record the quotient 1 as the next digit in the result. 
Result so far: 8521.0
Subtract 42 from 83 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 7:
410 divided by 42 is 9 with a remainder of 32.
Use 9 as the next digit of our solution. 
Result so far: 8521.9
Subtract 378 from 410 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 8:
42 can be fit into 320 7 times, resulting in a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 8521.97
If we subtract 294 from 320, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 9:
If we divide 260 by 42, we get 6 and a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 8521.976
Deduct 252 from 260 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
80 divided by 42 is 1 with a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 8521.9761
If we take 42 away from 80, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 11:
When dividing 380 by 42, we get 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 8521.97619
The remainder is 2 after subtracting 378 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 12:
If we divide 20 by 42, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 8521.97619
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
42 can be fit into 200 4 times, resulting in a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 8521.9761904
The remainder is 32 after subtracting 168 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 14:
If we divide 320 by 42, we get 7 and a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 8521.97619047
Deduct 294 from 320 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Our division results in 8521.97619047 with a remaining 2.6e-08.
