We look at the division of 72621579 by 545 
We want to figure out the number of times 72621579 can be divided by 545.

Step 1:
If we divide 7 by 545, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 545

Let's proceed to step 2:
545 can be fit into 72 0 times, resulting in a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Take the next digit (6) from the dividend and append it to 72, then repeat: 726 / 545

On to step 3:
The number 545 fits into 726 1 times, leaving a remainder of 181.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 545 from 726 leaves us with 181.
Take the next digit (2) from the dividend and append it to 181, then repeat: 1812 / 545

On to step 4:
545 goes into 1812 3 times with a remainder of 177.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 1635 from 1812 and we're left with 177.
Append the next digit (1) from the dividend to 177 and continue with: 1771 / 545

Moving on to step 5:
545 can be fit into 1771 3 times, resulting in a remainder of 136.
Put 3 as the next digit of the answer. 
Result so far: 133.0
If we subtract 1635 from 1771, we get 136.
Bring next digit (5) of the dividend behind the 136 and repeat the process: 1365 / 545

Going ahead to step 6:
When dividing 1365 by 545, we get 2 with a remainder of 275.
Record the quotient 2 as the next digit in the result. 
Result so far: 1332.0
Subtract 1090 from 1365 to get 275.
Grab the next digit (7) from the dividend, add it to 275, then carry on: 2757 / 545

Let's proceed to step 7:
When dividing 2757 by 545, we get 5 with a remainder of 32.
Write down 5 as next digit of the result. 
Result so far: 13325.0
If we take 2725 away from 2757, we end up with 32.
Grab the next digit (9) from the dividend, add it to 32, then carry on: 329 / 545

On to step 8:
545 goes into 329 0 times with a remainder of 329.
Write down 0 as next digit of the result. 
Result so far: 133250.0
If we take 0 away from 329, we end up with 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Moving on to step 9:
545 can be fit into 3290 6 times, resulting in a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 133250.6
Deduct 3270 from 3290 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
545 can be fit into 200 0 times, resulting in a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 133250.6
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 11:
545 goes into 2000 3 times with a remainder of 365.
Record the quotient 3 as the next digit in the result. 
Result so far: 133250.603
Deduct 1635 from 2000 and we're left with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Step 12:
3650 divided by 545 is 6 with a remainder of 380.
The next digit of our result is 6. 
Result so far: 133250.6036
Subtract 3270 from 3650 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 13:
545 goes into 3800 6 times with a remainder of 530.
Record the quotient 6 as the next digit in the result. 
Result so far: 133250.60366
Subtract 3270 from 3800 to get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

The quotient of the division is 133250.60366, and the remainder is 0.00053.
