We divide 90405544 by 138
We want to divide 90405544 by 138.

Advancing to step 1:
138 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 138

Advancing to step 2:
90 divided by 138 is 0 with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Fetch the next digit (4) from the dividend, attach it to 90 and continue: 904 / 138

Step 3:
138 can be fit into 904 6 times, resulting in a remainder of 76.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 828 from 904, we get 76.
Bring next digit (0) of the dividend behind the 76 and repeat the process: 760 / 138

Moving on to step 4:
The number 138 fits into 760 5 times, leaving a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
Subtracting 690 from 760 leaves us with 70.
Bring next digit (5) of the dividend behind the 70 and repeat the process: 705 / 138

On to step 5:
If we divide 705 by 138, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 655.0
If we subtract 690 from 705, we get 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 138

Let's proceed to step 6:
The number 138 fits into 155 1 times, leaving a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 6551.0
Subtract 138 from 155 to get 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 138

Moving on to step 7:
The number 138 fits into 174 1 times, leaving a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 65511.0
Subtract 138 from 174 to get 36.
Fetch the next digit (4) from the dividend, attach it to 36 and continue: 364 / 138

Moving on to step 8:
When dividing 364 by 138, we get 2 with a remainder of 88.
Record the quotient 2 as the next digit in the result. 
Result so far: 655112.0
The remainder is 88 after subtracting 276 from 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 9:
The number 138 fits into 880 6 times, leaving a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 655112.6
If we subtract 828 from 880, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 10:
If we divide 520 by 138, we get 3 and a remainder of 106.
Write down 3 as next digit of the result. 
Result so far: 655112.63
If we subtract 414 from 520, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 11:
138 can be fit into 1060 7 times, resulting in a remainder of 94.
The number 7 becomes the next digit in our result. 
Result so far: 655112.637
If we take 966 away from 1060, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 12:
138 goes into 940 6 times with a remainder of 112.
Put 6 as the next digit of the answer. 
Result so far: 655112.6376
The remainder is 112 after subtracting 828 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 13:
138 goes into 1120 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 655112.63768
Deduct 1104 from 1120 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.

Advancing to step 14:
If we divide 160 by 138, we get 1 and a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 655112.637681
Subtracting 138 from 160 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 15:
The number 138 fits into 220 1 times, leaving a remainder of 82.
The next digit of our result is 1. 
Result so far: 655112.6376811
Deduct 138 from 220 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

After the division, we end up with 655112.6376811 and a remainder of 8.2e-07.
