Let's divide 20148545 by 80
We're looking to find how many times 80 goes into 20148545.

Let's proceed to step 1:
If we divide 2 by 80, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 80

Let's proceed to step 2:
80 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 80

Step 3:
When dividing 201 by 80, we get 2 with a remainder of 41.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 160 from 201, we get 41.
Append the next digit (4) from the dividend to 41 and continue with: 414 / 80

Step 4:
414 divided by 80 is 5 with a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 25.0
Deduct 400 from 414 and we're left with 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 80

Advancing to step 5:
If we divide 148 by 80, we get 1 and a remainder of 68.
Write down 1 as next digit of the result. 
Result so far: 251.0
Subtracting 80 from 148 leaves us with 68.
Fetch the next digit (5) from the dividend, attach it to 68 and continue: 685 / 80

Advancing to step 6:
If we divide 685 by 80, we get 8 and a remainder of 45.
The next digit of our result is 8. 
Result so far: 2518.0
Subtract 640 from 685 to get 45.
Bring next digit (4) of the dividend behind the 45 and repeat the process: 454 / 80

On to step 7:
If we divide 454 by 80, we get 5 and a remainder of 54.
Put 5 as the next digit of the answer. 
Result so far: 25185.0
Deduct 400 from 454 and we're left with 54.
Grab the next digit (5) from the dividend, add it to 54, then carry on: 545 / 80

Advancing to step 8:
When dividing 545 by 80, we get 6 with a remainder of 65.
Record the quotient 6 as the next digit in the result. 
Result so far: 251856.0
Deduct 480 from 545 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 9:
The number 80 fits into 650 8 times, leaving a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 251856.8
The remainder is 10 after subtracting 640 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
80 goes into 100 1 times with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 251856.81
Subtract 80 from 100 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
When dividing 200 by 80, we get 2 with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 251856.812
Deduct 160 from 200 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
80 goes into 400 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 251856.8125
If we take 400 away from 400, 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.

On to step 13:
80 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 251856.8125
If we subtract 0 from 0, we 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 14:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 251856.8125
If we subtract 0 from 0, we 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.

The quotient of the division is 251856.8125, and the remainder is 0.0.
