We look at the division of 379836 by 87 
We want to figure out the number of times 379836 can be divided by 87.

Going ahead to step 1:
The number 87 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 87

Advancing to step 2:
87 goes into 37 0 times with a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Fetch the next digit (9) from the dividend, attach it to 37 and continue: 379 / 87

Advancing to step 3:
When dividing 379 by 87, we get 4 with a remainder of 31.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 348 from 379 and we're left with 31.
Take the next digit (8) from the dividend and append it to 31, then repeat: 318 / 87

Advancing to step 4:
If we divide 318 by 87, we get 3 and a remainder of 57.
The next digit of our result is 3. 
Result so far: 43.0
The remainder is 57 after subtracting 261 from 318.
Grab the next digit (3) from the dividend, add it to 57, then carry on: 573 / 87

Step 5:
87 goes into 573 6 times with a remainder of 51.
Put 6 as the next digit of the answer. 
Result so far: 436.0
Deduct 522 from 573 and we're left with 51.
Grab the next digit (6) from the dividend, add it to 51, then carry on: 516 / 87

On to step 6:
The number 87 fits into 516 5 times, leaving a remainder of 81.
The number 5 becomes the next digit in our result. 
Result so far: 4365.0
The remainder is 81 after subtracting 435 from 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 7:
810 divided by 87 is 9 with a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 4365.9
Deduct 783 from 810 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 8:
The number 87 fits into 270 3 times, leaving a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 4365.93
Deduct 261 from 270 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
When dividing 90 by 87, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 4365.931
If we subtract 87 from 90, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 10:
30 divided by 87 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 4365.931
If we take 0 away from 30, 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 11:
When dividing 300 by 87, we get 3 with a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 4365.93103
Subtracting 261 from 300 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 12:
The number 87 fits into 390 4 times, leaving a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 4365.931034
If we subtract 348 from 390, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 13:
If we divide 420 by 87, we get 4 and a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 4365.9310344
Subtract 348 from 420 to 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.

After the division, we end up with 4365.9310344 and a remainder of 7.2e-07.
