We're dividing 438623 by 58 
We want to figure out the number of times 438623 can be divided by 58.

On to step 1:
The number 58 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 58

Advancing to step 2:
43 divided by 58 is 0 with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Grab the next digit (8) from the dividend, add it to 43, then carry on: 438 / 58

Advancing to step 3:
438 divided by 58 is 7 with a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 32 after subtracting 406 from 438.
Grab the next digit (6) from the dividend, add it to 32, then carry on: 326 / 58

Let's proceed to step 4:
58 can be fit into 326 5 times, resulting in a remainder of 36.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
Deduct 290 from 326 and we're left with 36.
Grab the next digit (2) from the dividend, add it to 36, then carry on: 362 / 58

Going ahead to step 5:
The number 58 fits into 362 6 times, leaving a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 756.0
Deduct 348 from 362 and we're left with 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 58

Moving on to step 6:
The number 58 fits into 143 2 times, leaving a remainder of 27.
Put 2 as the next digit of the answer. 
Result so far: 7562.0
If we subtract 116 from 143, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 7:
If we divide 270 by 58, we get 4 and a remainder of 38.
The next digit of our result is 4. 
Result so far: 7562.4
Subtracting 232 from 270 leaves us 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.

Moving on to step 8:
58 goes into 380 6 times with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 7562.46
If we subtract 348 from 380, we 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.

Moving on to step 9:
The number 58 fits into 320 5 times, leaving a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 7562.465
If we take 290 away from 320, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
The number 58 fits into 300 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 7562.4655
Subtract 290 from 300 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 7562.4655, and the remainder is 0.0001.
