We're dividing 90588339 by 139 
Let's see how many times 139 fits into 90588339.

Step 1:
139 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 139

Moving on to step 2:
139 goes into 90 0 times with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Include the next digit (5) from the dividend after 90, then repeat: 905 / 139

Moving on to step 3:
139 goes into 905 6 times with a remainder of 71.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 71 after subtracting 834 from 905.
Grab the next digit (8) from the dividend, add it to 71, then carry on: 718 / 139

Let's proceed to step 4:
If we divide 718 by 139, we get 5 and a remainder of 23.
The next digit of our result is 5. 
Result so far: 65.0
The remainder is 23 after subtracting 695 from 718.
Bring next digit (8) of the dividend behind the 23 and repeat the process: 238 / 139

Step 5:
139 goes into 238 1 times with a remainder of 99.
Write down 1 as next digit of the result. 
Result so far: 651.0
Deduct 139 from 238 and we're left with 99.
Include the next digit (3) from the dividend after 99, then repeat: 993 / 139

Let's proceed to step 6:
139 goes into 993 7 times with a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 6517.0
If we subtract 973 from 993, we get 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 139

Moving on to step 7:
203 divided by 139 is 1 with a remainder of 64.
Use 1 as the next digit of our solution. 
Result so far: 65171.0
Subtract 139 from 203 to get 64.
Bring next digit (9) of the dividend behind the 64 and repeat the process: 649 / 139

On to step 8:
When dividing 649 by 139, we get 4 with a remainder of 93.
Record the quotient 4 as the next digit in the result. 
Result so far: 651714.0
Subtract 556 from 649 to get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Advancing to step 9:
The number 139 fits into 930 6 times, leaving a remainder of 96.
Write down 6 as next digit of the result. 
Result so far: 651714.6
If we take 834 away from 930, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 10:
When dividing 960 by 139, we get 6 with a remainder of 126.
Put 6 as the next digit of the answer. 
Result so far: 651714.66
If we subtract 834 from 960, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

The final result is 651714.66 with a remainder of 0.126.
