139557 ÷ 89 
We want to divide 139557 by 89.

Step 1:
The number 89 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 89

Going ahead to step 2:
When dividing 13 by 89, we get 0 with 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.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 89

Moving on to step 3:
139 divided by 89 is 1 with a remainder of 50.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 89 away from 139, we end up with 50.
Include the next digit (5) from the dividend after 50, then repeat: 505 / 89

Moving on to step 4:
If we divide 505 by 89, we get 5 and a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 445 away from 505, we end up with 60.
Grab the next digit (5) from the dividend, add it to 60, then carry on: 605 / 89

Advancing to step 5:
605 divided by 89 is 6 with a remainder of 71.
Put 6 as the next digit of the answer. 
Result so far: 156.0
Subtract 534 from 605 to get 71.
Append the next digit (7) from the dividend to 71 and continue with: 717 / 89

Let's proceed to step 6:
When dividing 717 by 89, we get 8 with a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 1568.0
If we subtract 712 from 717, 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.

On to step 7:
If we divide 50 by 89, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 1568.0
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.

Moving on to step 8:
500 divided by 89 is 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 1568.05
The remainder is 55 after subtracting 445 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 9:
550 divided by 89 is 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 1568.056
Deduct 534 from 550 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
The number 89 fits into 160 1 times, leaving a remainder of 71.
The number 1 becomes the next digit in our result. 
Result so far: 1568.0561
If we take 89 away from 160, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 11:
89 can be fit into 710 7 times, resulting in a remainder of 87.
The number 7 becomes the next digit in our result. 
Result so far: 1568.05617
Deduct 623 from 710 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Step 12:
When dividing 870 by 89, we get 9 with a remainder of 69.
The number 9 becomes the next digit in our result. 
Result so far: 1568.056179
Deduct 801 from 870 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 13:
The number 89 fits into 690 7 times, leaving a remainder of 67.
Record the quotient 7 as the next digit in the result. 
Result so far: 1568.0561797
If we take 623 away from 690, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 14:
89 goes into 670 7 times with a remainder of 47.
Use 7 as the next digit of our solution. 
Result so far: 1568.05617977
If we take 623 away from 670, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The final outcome is 1568.05617977, with a leftover of 4.7e-08.
