We're dividing 21693358 by 138 
Our goal is to divide 21693358 by 138.

Step 1:
The number 138 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 138

Let's proceed to step 2:
138 goes into 21 0 times with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 138

Let's proceed to step 3:
When dividing 216 by 138, we get 1 with a remainder of 78.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 78 after subtracting 138 from 216.
Grab the next digit (9) from the dividend, add it to 78, then carry on: 789 / 138

Going ahead to step 4:
If we divide 789 by 138, we get 5 and a remainder of 99.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 690 from 789, we get 99.
Append the next digit (3) from the dividend to 99 and continue with: 993 / 138

Going ahead to step 5:
138 goes into 993 7 times with a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 157.0
If we subtract 966 from 993, we get 27.
Include the next digit (3) from the dividend after 27, then repeat: 273 / 138

Advancing to step 6:
138 can be fit into 273 1 times, resulting in a remainder of 135.
Write down 1 as next digit of the result. 
Result so far: 1571.0
If we subtract 138 from 273, we get 135.
Include the next digit (5) from the dividend after 135, then repeat: 1355 / 138

Going ahead to step 7:
When dividing 1355 by 138, we get 9 with a remainder of 113.
The number 9 becomes the next digit in our result. 
Result so far: 15719.0
If we take 1242 away from 1355, we end up with 113.
Append the next digit (8) from the dividend to 113 and continue with: 1138 / 138

Moving on to step 8:
When dividing 1138 by 138, we get 8 with a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 157198.0
Subtract 1104 from 1138 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 9:
When dividing 340 by 138, we get 2 with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 157198.2
If we subtract 276 from 340, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 10:
When dividing 640 by 138, we get 4 with a remainder of 88.
Write down 4 as next digit of the result. 
Result so far: 157198.24
If we subtract 552 from 640, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 11:
138 goes into 880 6 times with a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 157198.246
Subtract 828 from 880 to 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.

Let's proceed to step 12:
If we divide 520 by 138, we get 3 and a remainder of 106.
The next digit of our result is 3. 
Result so far: 157198.2463
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 13:
138 can be fit into 1060 7 times, resulting in a remainder of 94.
Record the quotient 7 as the next digit in the result. 
Result so far: 157198.24637
Subtracting 966 from 1060 leaves us 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.

Moving on to step 14:
When dividing 940 by 138, we get 6 with a remainder of 112.
Use 6 as the next digit of our solution. 
Result so far: 157198.246376
If we take 828 away from 940, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 15:
1120 divided by 138 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 157198.2463768
If we take 1104 away from 1120, we end up 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 16:
The number 138 fits into 160 1 times, leaving a remainder of 22.
The next digit of our result is 1. 
Result so far: 157198.24637681
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.

The quotient of the division is 157198.24637681, and the remainder is 2.2e-08.
