584 can be fit into 4395 7 times, resulting in a remainder of 307.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 4088 from 4395 and we're left with 307.
Bring next digit (3) of the dividend behind the 307 and repeat the process: 3073 / 584

Moving on to step 5:
The number 584 fits into 3073 5 times, leaving a remainder of 153.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
Subtract 2920 from 3073 to get 153.
Include the next digit (8) from the dividend after 153, then repeat: 1538 / 584

On to step 6:
1538 divided by 584 is 2 with a remainder of 370.
Use 2 as the next digit of our solution. 
Result so far: 752.0
If we subtract 1168 from 1538, we get 370.
Include the next digit (0) from the dividend after 370, then repeat: 3700 / 584

Going ahead to step 7:
584 goes into 3700 6 times with a remainder of 196.
The next digit of our result is 6. 
Result so far: 7526.0
Deduct 3504 from 3700 and we're left with 196.
Bring next digit (1) of the dividend behind the 196 and repeat the process: 1961 / 584

Going ahead to step 8:
584 can be fit into 1961 3 times, resulting in a remainder of 209.
Record the quotient 3 as the next digit in the result. 
Result so far: 75263.0
Subtract 1752 from 1961 to get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Let's proceed to step 9:
When dividing 2090 by 584, we get 3 with a remainder of 338.
Use 3 as the next digit of our solution. 
Result so far: 75263.3
If we subtract 1752 from 2090, we get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Advancing to step 10:
When dividing 3380 by 584, we get 5 with a remainder of 460.
Write down 5 as next digit of the result. 
Result so far: 75263.35
Subtracting 2920 from 3380 leaves us with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 11:
584 can be fit into 4600 7 times, resulting in a remainder of 512.
Record the quotient 7 as the next digit in the result. 
Result so far: 75263.357
Deduct 4088 from 4600 and we're left with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Advancing to step 12:
5120 divided by 584 is 8 with a remainder of 448.
Use 8 as the next digit of our solution. 
Result so far: 75263.3578
If we take 4672 away from 5120, we end up with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Advancing to step 13:
4480 divided by 584 is 7 with a remainder of 392.
Use 7 as the next digit of our solution. 
Result so far: 75263.35787
If we take 4088 away from 4480, we end up with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Going ahead to step 14:
If we divide 3920 by 584, we get 6 and a remainder of 416.
Write down 6 as next digit of the result. 
Result so far: 75263.357876
If we subtract 3504 from 3920, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Advancing to step 15:
4160 divided by 584 is 7 with a remainder of 72.
Use 7 as the next digit of our solution. 
Result so far: 75263.3578767
If we subtract 4088 from 4160, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 16:
584 can be fit into 720 1 times, resulting in a remainder of 136.
The number 1 becomes the next digit in our result. 
Result so far: 75263.35787671
Subtract 584 from 720 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

The quotient of the division is 75263.35787671, and the remainder is 1.36e-07.
