Let's divide 258345 by 74
We want to figure out the number of times 258345 can be divided by 74.

Going ahead to step 1:
74 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 74

Step 2:
25 divided by 74 is 0 with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Bring next digit (8) of the dividend behind the 25 and repeat the process: 258 / 74

Advancing to step 3:
When dividing 258 by 74, we get 3 with a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 222 from 258 and we're left with 36.
Grab the next digit (3) from the dividend, add it to 36, then carry on: 363 / 74

Step 4:
74 can be fit into 363 4 times, resulting in a remainder of 67.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
If we subtract 296 from 363, we get 67.
Include the next digit (4) from the dividend after 67, then repeat: 674 / 74

On to step 5:
674 divided by 74 is 9 with a remainder of 8.
The next digit of our result is 9. 
Result so far: 349.0
If we subtract 666 from 674, we get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 74

Step 6:
74 goes into 85 1 times with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 3491.0
Deduct 74 from 85 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
74 goes into 110 1 times with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 3491.1
Subtract 74 from 110 to get 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 8:
The number 74 fits into 360 4 times, leaving a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 3491.14
The remainder is 64 after subtracting 296 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 9:
640 divided by 74 is 8 with a remainder of 48.
The next digit of our result is 8. 
Result so far: 3491.148
Subtract 592 from 640 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 10:
When dividing 480 by 74, we get 6 with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 3491.1486
Deduct 444 from 480 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.

Let's proceed to step 11:
74 can be fit into 360 4 times, resulting in a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 3491.14864
Deduct 296 from 360 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 12:
When dividing 640 by 74, we get 8 with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 3491.148648
If we subtract 592 from 640, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 13:
480 divided by 74 is 6 with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 3491.1486486
Deduct 444 from 480 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.

Let's proceed to step 14:
360 divided by 74 is 4 with a remainder of 64.
The next digit of our result is 4. 
Result so far: 3491.14864864
If we subtract 296 from 360, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 3491.14864864 and a remainder of 6.4e-08.
