90145122 divided by 139 
Let's see how many times 139 fits into 90145122.

Let's proceed to step 1:
139 goes into 9 0 times with 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.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 139

Advancing to step 2:
90 divided by 139 is 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Fetch the next digit (1) from the dividend, attach it to 90 and continue: 901 / 139

Step 3:
If we divide 901 by 139, we get 6 and a remainder of 67.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 834 from 901 to get 67.
Bring next digit (4) of the dividend behind the 67 and repeat the process: 674 / 139

Let's proceed to step 4:
The number 139 fits into 674 4 times, leaving a remainder of 118.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
Subtract 556 from 674 to get 118.
Bring next digit (5) of the dividend behind the 118 and repeat the process: 1185 / 139

Moving on to step 5:
1185 divided by 139 is 8 with a remainder of 73.
Put 8 as the next digit of the answer. 
Result so far: 648.0
Deduct 1112 from 1185 and we're left with 73.
Grab the next digit (1) from the dividend, add it to 73, then carry on: 731 / 139

Let's proceed to step 6:
731 divided by 139 is 5 with a remainder of 36.
The next digit of our result is 5. 
Result so far: 6485.0
If we subtract 695 from 731, we get 36.
Bring next digit (2) of the dividend behind the 36 and repeat the process: 362 / 139

Step 7:
The number 139 fits into 362 2 times, leaving a remainder of 84.
Write down 2 as next digit of the result. 
Result so far: 64852.0
Subtracting 278 from 362 leaves us with 84.
Bring next digit (2) of the dividend behind the 84 and repeat the process: 842 / 139

Let's proceed to step 8:
139 goes into 842 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 648526.0
If we take 834 away from 842, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
80 divided by 139 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 648526.0
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 10:
139 goes into 800 5 times with a remainder of 105.
The number 5 becomes the next digit in our result. 
Result so far: 648526.05
If we subtract 695 from 800, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 11:
If we divide 1050 by 139, we get 7 and a remainder of 77.
The number 7 becomes the next digit in our result. 
Result so far: 648526.057
Subtracting 973 from 1050 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 12:
139 goes into 770 5 times with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 648526.0575
If we subtract 695 from 770, we 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.

Step 13:
750 divided by 139 is 5 with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 648526.05755
If we take 695 away from 750, 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.

In conclusion, the division gives 648526.05755 with a balance of 5.5e-05.
