We're dividing 16397945 by 155 
We want to divide 16397945 by 155.

Step 1:
The number 155 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 155

Advancing to step 2:
When dividing 16 by 155, we get 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 155

Advancing to step 3:
155 can be fit into 163 1 times, resulting in a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 155 from 163 and we're left with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 155

Step 4:
If we divide 89 by 155, we get 0 and a remainder of 89.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 89 leaves us with 89.
Include the next digit (7) from the dividend after 89, then repeat: 897 / 155

On to step 5:
If we divide 897 by 155, we get 5 and a remainder of 122.
Write down 5 as next digit of the result. 
Result so far: 105.0
If we subtract 775 from 897, we get 122.
Take the next digit (9) from the dividend and append it to 122, then repeat: 1229 / 155

Going ahead to step 6:
155 goes into 1229 7 times with a remainder of 144.
Write down 7 as next digit of the result. 
Result so far: 1057.0
The remainder is 144 after subtracting 1085 from 1229.
Grab the next digit (4) from the dividend, add it to 144, then carry on: 1444 / 155

On to step 7:
155 can be fit into 1444 9 times, resulting in a remainder of 49.
Record the quotient 9 as the next digit in the result. 
Result so far: 10579.0
If we take 1395 away from 1444, we end up with 49.
Fetch the next digit (5) from the dividend, attach it to 49 and continue: 495 / 155

Let's proceed to step 8:
495 divided by 155 is 3 with a remainder of 30.
The next digit of our result is 3. 
Result so far: 105793.0
Subtracting 465 from 495 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
The number 155 fits into 300 1 times, leaving a remainder of 145.
Put 1 as the next digit of the answer. 
Result so far: 105793.1
Subtracting 155 from 300 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Advancing to step 10:
1450 divided by 155 is 9 with a remainder of 55.
Use 9 as the next digit of our solution. 
Result so far: 105793.19
The remainder is 55 after subtracting 1395 from 1450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 11:
If we divide 550 by 155, we get 3 and a remainder of 85.
The next digit of our result is 3. 
Result so far: 105793.193
If we subtract 465 from 550, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 12:
When dividing 850 by 155, we get 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 105793.1935
Subtracting 775 from 850 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 13:
155 goes into 750 4 times with a remainder of 130.
Use 4 as the next digit of our solution. 
Result so far: 105793.19354
If we take 620 away from 750, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 14:
When dividing 1300 by 155, we get 8 with a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 105793.193548
Subtracting 1240 from 1300 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 15:
When dividing 600 by 155, we get 3 with a remainder of 135.
Write down 3 as next digit of the result. 
Result so far: 105793.1935483
If we subtract 465 from 600, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 16:
If we divide 1350 by 155, we get 8 and a remainder of 110.
The number 8 becomes the next digit in our result. 
Result so far: 105793.19354838
If we take 1240 away from 1350, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

After the division, we end up with 105793.19354838 and a remainder of 1.1e-07.
