We divide 319458 by 87
We want to figure out the number of times 319458 can be divided by 87.

On to step 1:
87 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 87

On to step 2:
The number 87 fits into 31 0 times, leaving a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Fetch the next digit (9) from the dividend, attach it to 31 and continue: 319 / 87

Going ahead to step 3:
319 divided by 87 is 3 with a remainder of 58.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 261 from 319 and we're left with 58.
Bring next digit (4) of the dividend behind the 58 and repeat the process: 584 / 87

On to step 4:
87 goes into 584 6 times with a remainder of 62.
The next digit of our result is 6. 
Result so far: 36.0
Subtracting 522 from 584 leaves us with 62.
Grab the next digit (5) from the dividend, add it to 62, then carry on: 625 / 87

On to step 5:
87 goes into 625 7 times with a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 367.0
Subtracting 609 from 625 leaves us with 16.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 87

Step 6:
The number 87 fits into 168 1 times, leaving a remainder of 81.
The next digit of our result is 1. 
Result so far: 3671.0
Subtracting 87 from 168 leaves us with 81.
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:
87 can be fit into 810 9 times, resulting in a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 3671.9
If we take 783 away from 810, we end up 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.

Moving on to step 8:
If we divide 270 by 87, we get 3 and a remainder of 9.
The next digit of our result is 3. 
Result so far: 3671.93
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.

Let's proceed to step 9:
If we divide 90 by 87, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 3671.931
The remainder is 3 after subtracting 87 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
When dividing 30 by 87, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 3671.931
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
If we divide 300 by 87, we get 3 and a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 3671.93103
Subtract 261 from 300 to get 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.
Use 4 as the next digit of our solution. 
Result so far: 3671.931034
Deduct 348 from 390 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 13:
When dividing 420 by 87, we get 4 with a remainder of 72.
Use 4 as the next digit of our solution. 
Result so far: 3671.9310344
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.

The quotient of the division is 3671.9310344, and the remainder is 7.2e-07.
