We look at the division of 42339974 by 585 
Our goal is to divide 42339974 by 585.

Let's proceed to step 1:
4 divided by 585 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 585

Step 2:
The number 585 fits into 42 0 times, leaving a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Bring next digit (3) of the dividend behind the 42 and repeat the process: 423 / 585

Step 3:
The number 585 fits into 423 0 times, leaving a remainder of 423.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 423 and we're left with 423.
Append the next digit (3) from the dividend to 423 and continue with: 4233 / 585

Step 4:
The number 585 fits into 4233 7 times, leaving a remainder of 138.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 138 after subtracting 4095 from 4233.
Grab the next digit (9) from the dividend, add it to 138, then carry on: 1389 / 585

Step 5:
The number 585 fits into 1389 2 times, leaving a remainder of 219.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
If we subtract 1170 from 1389, we get 219.
Grab the next digit (9) from the dividend, add it to 219, then carry on: 2199 / 585

Step 6:
If we divide 2199 by 585, we get 3 and a remainder of 444.
Write down 3 as next digit of the result. 
Result so far: 723.0
The remainder is 444 after subtracting 1755 from 2199.
Grab the next digit (7) from the dividend, add it to 444, then carry on: 4447 / 585

On to step 7:
4447 divided by 585 is 7 with a remainder of 352.
Write down 7 as next digit of the result. 
Result so far: 7237.0
Subtracting 4095 from 4447 leaves us with 352.
Append the next digit (4) from the dividend to 352 and continue with: 3524 / 585

On to step 8:
The number 585 fits into 3524 6 times, leaving a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 72376.0
If we take 3510 away from 3524, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
The number 585 fits into 140 0 times, leaving a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 72376.0
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 10:
The number 585 fits into 1400 2 times, leaving a remainder of 230.
The number 2 becomes the next digit in our result. 
Result so far: 72376.02
Subtract 1170 from 1400 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 11:
585 can be fit into 2300 3 times, resulting in a remainder of 545.
Use 3 as the next digit of our solution. 
Result so far: 72376.023
If we take 1755 away from 2300, we end up with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Step 12:
5450 divided by 585 is 9 with a remainder of 185.
Record the quotient 9 as the next digit in the result. 
Result so far: 72376.0239
Subtract 5265 from 5450 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 13:
The number 585 fits into 1850 3 times, leaving a remainder of 95.
Use 3 as the next digit of our solution. 
Result so far: 72376.02393
Subtract 1755 from 1850 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 14:
950 divided by 585 is 1 with a remainder of 365.
Write down 1 as next digit of the result. 
Result so far: 72376.023931
Subtract 585 from 950 to get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Going ahead to step 15:
The number 585 fits into 3650 6 times, leaving a remainder of 140.
Record the quotient 6 as the next digit in the result. 
Result so far: 72376.0239316
Subtracting 3510 from 3650 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 16:
The number 585 fits into 1400 2 times, leaving a remainder of 230.
Put 2 as the next digit of the answer. 
Result so far: 72376.02393162
If we take 1170 away from 1400, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

After the division, we end up with 72376.02393162 and a remainder of 2.3e-07.
