139958 ÷ 89 
We want to divide 139958 by 89.

Moving on to step 1:
89 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 89

Moving on to step 2:
If we divide 13 by 89, we get 0 and a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 89

Let's proceed to step 3:
If we divide 139 by 89, we get 1 and a remainder of 50.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 89 from 139 leaves us with 50.
Append the next digit (9) from the dividend to 50 and continue with: 509 / 89

Advancing to step 4:
509 divided by 89 is 5 with a remainder of 64.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtract 445 from 509 to get 64.
Append the next digit (5) from the dividend to 64 and continue with: 645 / 89

Going ahead to step 5:
89 goes into 645 7 times with a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 157.0
If we subtract 623 from 645, we get 22.
Take the next digit (8) from the dividend and append it to 22, then repeat: 228 / 89

Let's proceed to step 6:
228 divided by 89 is 2 with a remainder of 50.
Use 2 as the next digit of our solution. 
Result so far: 1572.0
Deduct 178 from 228 and we're left 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.

On to step 7:
500 divided by 89 is 5 with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 1572.5
If we take 445 away from 500, we end up 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.

Step 8:
When dividing 550 by 89, we get 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 1572.56
Subtracting 534 from 550 leaves us 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.

Going ahead to step 9:
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: 1572.561
The remainder is 71 after subtracting 89 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 10:
89 goes into 710 7 times with a remainder of 87.
Write down 7 as next digit of the result. 
Result so far: 1572.5617
The remainder is 87 after subtracting 623 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Let's proceed to step 11:
89 can be fit into 870 9 times, resulting in a remainder of 69.
The number 9 becomes the next digit in our result. 
Result so far: 1572.56179
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.

On to step 12:
89 goes into 690 7 times with a remainder of 67.
Put 7 as the next digit of the answer. 
Result so far: 1572.561797
Subtracting 623 from 690 leaves us 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.

Let's proceed to step 13:
If we divide 670 by 89, we get 7 and a remainder of 47.
The number 7 becomes the next digit in our result. 
Result so far: 1572.5617977
The remainder is 47 after subtracting 623 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Our division results in 1572.5617977 with a remaining 4.7e-07.
