We divide 20871921 by 168
Our goal is to divide 20871921 by 168.

Advancing to step 1:
The number 168 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 168

On to step 2:
168 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Include the next digit (8) from the dividend after 20, then repeat: 208 / 168

Step 3:
208 divided by 168 is 1 with a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 168 from 208, we get 40.
Take the next digit (7) from the dividend and append it to 40, then repeat: 407 / 168

Step 4:
168 goes into 407 2 times with a remainder of 71.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 336 away from 407, we end up with 71.
Fetch the next digit (1) from the dividend, attach it to 71 and continue: 711 / 168

Moving on to step 5:
711 divided by 168 is 4 with a remainder of 39.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
The remainder is 39 after subtracting 672 from 711.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 168

Advancing to step 6:
When dividing 399 by 168, we get 2 with a remainder of 63.
The number 2 becomes the next digit in our result. 
Result so far: 1242.0
Deduct 336 from 399 and we're left with 63.
Take the next digit (2) from the dividend and append it to 63, then repeat: 632 / 168

Advancing to step 7:
168 can be fit into 632 3 times, resulting in a remainder of 128.
Write down 3 as next digit of the result. 
Result so far: 12423.0
Subtract 504 from 632 to get 128.
Fetch the next digit (1) from the dividend, attach it to 128 and continue: 1281 / 168

Moving on to step 8:
168 goes into 1281 7 times with a remainder of 105.
Write down 7 as next digit of the result. 
Result so far: 124237.0
If we take 1176 away from 1281, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 9:
The number 168 fits into 1050 6 times, leaving a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 124237.6
The remainder is 42 after subtracting 1008 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
420 divided by 168 is 2 with a remainder of 84.
Use 2 as the next digit of our solution. 
Result so far: 124237.62
The remainder is 84 after subtracting 336 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 11:
840 divided by 168 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 124237.625
Deduct 840 from 840 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
168 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 124237.625
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 13:
If we divide 0 by 168, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 124237.625
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 124237.625 with a remaining 0.0.
