16994174 divided by 86 
We want to divide 16994174 by 86.

Moving on to step 1:
1 divided by 86 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 86

Moving on to step 2:
When dividing 16 by 86, we get 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 86

Advancing to step 3:
When dividing 169 by 86, we get 1 with a remainder of 83.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 83 after subtracting 86 from 169.
Take the next digit (9) from the dividend and append it to 83, then repeat: 839 / 86

Advancing to step 4:
The number 86 fits into 839 9 times, leaving a remainder of 65.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Deduct 774 from 839 and we're left with 65.
Include the next digit (4) from the dividend after 65, then repeat: 654 / 86

Let's proceed to step 5:
When dividing 654 by 86, we get 7 with a remainder of 52.
The next digit of our result is 7. 
Result so far: 197.0
If we subtract 602 from 654, we get 52.
Append the next digit (1) from the dividend to 52 and continue with: 521 / 86

Step 6:
When dividing 521 by 86, we get 6 with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 1976.0
Deduct 516 from 521 and we're left with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 86

Going ahead to step 7:
86 goes into 57 0 times with a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 19760.0
If we take 0 away from 57, we end up with 57.
Grab the next digit (4) from the dividend, add it to 57, then carry on: 574 / 86

On to step 8:
574 divided by 86 is 6 with a remainder of 58.
Use 6 as the next digit of our solution. 
Result so far: 197606.0
If we subtract 516 from 574, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 9:
When dividing 580 by 86, we get 6 with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 197606.6
Deduct 516 from 580 and we're left with 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:
86 can be fit into 640 7 times, resulting in a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 197606.67
Deduct 602 from 640 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 11:
The number 86 fits into 380 4 times, leaving a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 197606.674
Subtracting 344 from 380 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 12:
If we divide 360 by 86, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 197606.6744
Subtracting 344 from 360 leaves us 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.

After the division, we end up with 197606.6744 and a remainder of 0.00016.
