We're dividing 139498 by 87 
We want to figure out the number of times 139498 can be divided by 87.

Moving on to step 1:
If we divide 1 by 87, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 87

Let's proceed to step 2:
The number 87 fits into 13 0 times, leaving a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 87

Step 3:
87 can be fit into 139 1 times, resulting in a remainder of 52.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 87 from 139, we get 52.
Append the next digit (4) from the dividend to 52 and continue with: 524 / 87

On to step 4:
87 can be fit into 524 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtract 522 from 524 to get 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 87

Let's proceed to step 5:
The number 87 fits into 29 0 times, leaving a remainder of 29.
The next digit of our result is 0. 
Result so far: 160.0
Subtracting 0 from 29 leaves us with 29.
Grab the next digit (8) from the dividend, add it to 29, then carry on: 298 / 87

Step 6:
298 divided by 87 is 3 with a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 1603.0
If we subtract 261 from 298, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 7:
87 can be fit into 370 4 times, resulting in a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 1603.4
If we take 348 away from 370, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 8:
When dividing 220 by 87, we get 2 with a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 1603.42
Subtract 174 from 220 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 9:
87 can be fit into 460 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 1603.425
The remainder is 25 after subtracting 435 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 10:
250 divided by 87 is 2 with a remainder of 76.
The number 2 becomes the next digit in our result. 
Result so far: 1603.4252
Subtracting 174 from 250 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 11:
If we divide 760 by 87, we get 8 and a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 1603.42528
Subtract 696 from 760 to 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.

Advancing to step 12:
If we divide 640 by 87, we get 7 and a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 1603.425287
The remainder is 31 after subtracting 609 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 13:
The number 87 fits into 310 3 times, leaving a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 1603.4252873
If we subtract 261 from 310, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 14:
490 divided by 87 is 5 with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 1603.42528735
Subtracting 435 from 490 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final result is 1603.42528735 with a remainder of 5.5e-08.
