We look at the division of 149916 by 84 
We want to figure out the number of times 149916 can be divided by 84.

Step 1:
If we divide 1 by 84, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 84

Advancing to step 2:
If we divide 14 by 84, we get 0 and a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 84

Moving on to step 3:
If we divide 149 by 84, we get 1 and a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 84 from 149 leaves us with 65.
Take the next digit (9) from the dividend and append it to 65, then repeat: 659 / 84

Advancing to step 4:
84 can be fit into 659 7 times, resulting in a remainder of 71.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Deduct 588 from 659 and we're left with 71.
Grab the next digit (1) from the dividend, add it to 71, then carry on: 711 / 84

Advancing to step 5:
84 can be fit into 711 8 times, resulting in a remainder of 39.
Use 8 as the next digit of our solution. 
Result so far: 178.0
If we subtract 672 from 711, we get 39.
Grab the next digit (6) from the dividend, add it to 39, then carry on: 396 / 84

Let's proceed to step 6:
The number 84 fits into 396 4 times, leaving a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 1784.0
The remainder is 60 after subtracting 336 from 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 7:
600 divided by 84 is 7 with a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 1784.7
Deduct 588 from 600 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
84 can be fit into 120 1 times, resulting in a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 1784.71
Subtract 84 from 120 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
84 can be fit into 360 4 times, resulting in a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 1784.714
If we subtract 336 from 360, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
When dividing 240 by 84, we get 2 with a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 1784.7142
Subtracting 168 from 240 leaves us 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.

Step 11:
When dividing 720 by 84, we get 8 with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 1784.71428
Subtracting 672 from 720 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 12:
When dividing 480 by 84, we get 5 with a remainder of 60.
The next digit of our result is 5. 
Result so far: 1784.714285
If we take 420 away from 480, we end up 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.

Going ahead to step 13:
If we divide 600 by 84, we get 7 and a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 1784.7142857
Subtracting 588 from 600 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 14:
120 divided by 84 is 1 with a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 1784.71428571
Subtracting 84 from 120 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.

The final outcome is 1784.71428571, with a leftover of 3.6e-08.
