16995969 ÷ 138 
We want to divide 16995969 by 138.

Step 1:
138 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 138

Step 2:
16 divided by 138 is 0 with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Grab the next digit (9) from the dividend, add it to 16, then carry on: 169 / 138

Advancing to step 3:
When dividing 169 by 138, we get 1 with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 138 from 169 and we're left with 31.
Bring next digit (9) of the dividend behind the 31 and repeat the process: 319 / 138

Let's proceed to step 4:
319 divided by 138 is 2 with a remainder of 43.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 43 after subtracting 276 from 319.
Include the next digit (5) from the dividend after 43, then repeat: 435 / 138

Step 5:
The number 138 fits into 435 3 times, leaving a remainder of 21.
The next digit of our result is 3. 
Result so far: 123.0
If we take 414 away from 435, we end up with 21.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 138

Advancing to step 6:
219 divided by 138 is 1 with a remainder of 81.
The next digit of our result is 1. 
Result so far: 1231.0
Subtract 138 from 219 to get 81.
Fetch the next digit (6) from the dividend, attach it to 81 and continue: 816 / 138

On to step 7:
138 goes into 816 5 times with a remainder of 126.
Put 5 as the next digit of the answer. 
Result so far: 12315.0
Subtract 690 from 816 to get 126.
Bring next digit (9) of the dividend behind the 126 and repeat the process: 1269 / 138

Moving on to step 8:
138 goes into 1269 9 times with a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 123159.0
Subtracting 1242 from 1269 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 9:
138 can be fit into 270 1 times, resulting in a remainder of 132.
Put 1 as the next digit of the answer. 
Result so far: 123159.1
The remainder is 132 after subtracting 138 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 10:
When dividing 1320 by 138, we get 9 with a remainder of 78.
Write down 9 as next digit of the result. 
Result so far: 123159.19
If we subtract 1242 from 1320, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 11:
138 goes into 780 5 times with a remainder of 90.
The number 5 becomes the next digit in our result. 
Result so far: 123159.195
Subtracting 690 from 780 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 12:
138 can be fit into 900 6 times, resulting in a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 123159.1956
If we take 828 away from 900, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 13:
138 goes into 720 5 times with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 123159.19565
Subtract 690 from 720 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 14:
300 divided by 138 is 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 123159.195652
If we take 276 away from 300, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 15:
When dividing 240 by 138, we get 1 with a remainder of 102.
Use 1 as the next digit of our solution. 
Result so far: 123159.1956521
Subtracting 138 from 240 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 16:
1020 divided by 138 is 7 with a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 123159.19565217
The remainder is 54 after subtracting 966 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 123159.19565217 with a remainder of 5.4e-08.
