We look at the division of 20889720 by 151 
Our goal is to divide 20889720 by 151.

Let's proceed to step 1:
The number 151 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 151

On to step 2:
When dividing 20 by 151, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Take the next digit (8) from the dividend and append it to 20, then repeat: 208 / 151

Advancing to step 3:
When dividing 208 by 151, we get 1 with a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 151 away from 208, we end up with 57.
Include the next digit (8) from the dividend after 57, then repeat: 578 / 151

Let's proceed to step 4:
151 can be fit into 578 3 times, resulting in a remainder of 125.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 453 from 578 leaves us with 125.
Fetch the next digit (9) from the dividend, attach it to 125 and continue: 1259 / 151

Step 5:
151 goes into 1259 8 times with a remainder of 51.
Use 8 as the next digit of our solution. 
Result so far: 138.0
If we subtract 1208 from 1259, we get 51.
Take the next digit (7) from the dividend and append it to 51, then repeat: 517 / 151

Step 6:
151 can be fit into 517 3 times, resulting in a remainder of 64.
Use 3 as the next digit of our solution. 
Result so far: 1383.0
Subtracting 453 from 517 leaves us with 64.
Grab the next digit (2) from the dividend, add it to 64, then carry on: 642 / 151

Let's proceed to step 7:
If we divide 642 by 151, we get 4 and a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 13834.0
Subtract 604 from 642 to get 38.
Fetch the next digit (0) from the dividend, attach it to 38 and continue: 380 / 151

Moving on to step 8:
380 divided by 151 is 2 with a remainder of 78.
Use 2 as the next digit of our solution. 
Result so far: 138342.0
The remainder is 78 after subtracting 302 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 9:
The number 151 fits into 780 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 138342.5
The remainder is 25 after subtracting 755 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 10:
250 divided by 151 is 1 with a remainder of 99.
Write down 1 as next digit of the result. 
Result so far: 138342.51
If we subtract 151 from 250, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 11:
151 can be fit into 990 6 times, resulting in a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 138342.516
If we subtract 906 from 990, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 12:
The number 151 fits into 840 5 times, leaving a remainder of 85.
The next digit of our result is 5. 
Result so far: 138342.5165
Subtract 755 from 840 to 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.

On to step 13:
If we divide 850 by 151, we get 5 and a remainder of 95.
The number 5 becomes the next digit in our result. 
Result so far: 138342.51655
Subtracting 755 from 850 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

The final outcome is 138342.51655, with a leftover of 9.5e-05.
