Let's divide 187890 by 79
We want to figure out the number of times 187890 can be divided by 79.

Let's proceed to step 1:
79 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 79

On to step 2:
When dividing 18 by 79, we get 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Grab the next digit (7) from the dividend, add it to 18, then carry on: 187 / 79

Moving on to step 3:
187 divided by 79 is 2 with a remainder of 29.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 158 from 187, we get 29.
Take the next digit (8) from the dividend and append it to 29, then repeat: 298 / 79

On to step 4:
298 divided by 79 is 3 with a remainder of 61.
The next digit of our result is 3. 
Result so far: 23.0
Subtracting 237 from 298 leaves us with 61.
Grab the next digit (9) from the dividend, add it to 61, then carry on: 619 / 79

Let's proceed to step 5:
When dividing 619 by 79, we get 7 with a remainder of 66.
The next digit of our result is 7. 
Result so far: 237.0
The remainder is 66 after subtracting 553 from 619.
Take the next digit (0) from the dividend and append it to 66, then repeat: 660 / 79

Going ahead to step 6:
The number 79 fits into 660 8 times, leaving a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 2378.0
If we subtract 632 from 660, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 7:
280 divided by 79 is 3 with a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 2378.3
Deduct 237 from 280 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 8:
The number 79 fits into 430 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 2378.35
Deduct 395 from 430 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 9:
79 can be fit into 350 4 times, resulting in a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 2378.354
Subtracting 316 from 350 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 10:
If we divide 340 by 79, we get 4 and a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 2378.3544
If we take 316 away from 340, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 2378.3544 with a remaining 0.00024.
