139087 ÷ 85 
Let's see how many times 85 fits into 139087.

Let's proceed to step 1:
If we divide 1 by 85, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 85

Moving on to step 2:
85 can be fit into 13 0 times, resulting in a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 85

Going ahead to step 3:
85 goes into 139 1 times with a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 54 after subtracting 85 from 139.
Take the next digit (0) from the dividend and append it to 54, then repeat: 540 / 85

Advancing to step 4:
85 goes into 540 6 times with a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 510 away from 540, we end up with 30.
Take the next digit (8) from the dividend and append it to 30, then repeat: 308 / 85

Moving on to step 5:
85 can be fit into 308 3 times, resulting in a remainder of 53.
The number 3 becomes the next digit in our result. 
Result so far: 163.0
If we take 255 away from 308, we end up with 53.
Fetch the next digit (7) from the dividend, attach it to 53 and continue: 537 / 85

Going ahead to step 6:
85 can be fit into 537 6 times, resulting in a remainder of 27.
Put 6 as the next digit of the answer. 
Result so far: 1636.0
If we subtract 510 from 537, 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.

Step 7:
85 can be fit into 270 3 times, resulting in a remainder of 15.
The next digit of our result is 3. 
Result so far: 1636.3
If we subtract 255 from 270, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
85 can be fit into 150 1 times, resulting in a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 1636.31
Subtract 85 from 150 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 9:
If we divide 650 by 85, we get 7 and a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 1636.317
Deduct 595 from 650 and we're left 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.

Going ahead to step 10:
85 goes into 550 6 times with a remainder of 40.
The next digit of our result is 6. 
Result so far: 1636.3176
Deduct 510 from 550 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
85 can be fit into 400 4 times, resulting in a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 1636.31764
If we subtract 340 from 400, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 12:
When dividing 600 by 85, we get 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 1636.317647
If we subtract 595 from 600, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 13:
When dividing 50 by 85, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 1636.317647
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 14:
When dividing 500 by 85, we get 5 with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 1636.31764705
Subtract 425 from 500 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The final outcome is 1636.31764705, with a leftover of 7.5e-08.
