When dividing 7 by 545, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 545

Moving on to step 2:
If we divide 75 by 545, we get 0 and a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Take the next digit (8) from the dividend and append it to 75, then repeat: 758 / 545

On to step 3:
545 can be fit into 758 1 times, resulting in a remainder of 213.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 545 from 758 and we're left with 213.
Bring next digit (8) of the dividend behind the 213 and repeat the process: 2138 / 545

Advancing to step 4:
2138 divided by 545 is 3 with a remainder of 503.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 1635 away from 2138, we end up with 503.
Bring next digit (6) of the dividend behind the 503 and repeat the process: 5036 / 545

Moving on to step 5:
The number 545 fits into 5036 9 times, leaving a remainder of 131.
Use 9 as the next digit of our solution. 
Result so far: 139.0
Subtracting 4905 from 5036 leaves us with 131.
Bring next digit (5) of the dividend behind the 131 and repeat the process: 1315 / 545

Let's proceed to step 6:
545 can be fit into 1315 2 times, resulting in a remainder of 225.
The number 2 becomes the next digit in our result. 
Result so far: 1392.0
Subtract 1090 from 1315 to get 225.
Append the next digit (7) from the dividend to 225 and continue with: 2257 / 545

Moving on to step 7:
545 goes into 2257 4 times with a remainder of 77.
Record the quotient 4 as the next digit in the result. 
Result so far: 13924.0
Subtract 2180 from 2257 to get 77.
Include the next digit (3) from the dividend after 77, then repeat: 773 / 545

On to step 8:
545 goes into 773 1 times with a remainder of 228.
Write down 1 as next digit of the result. 
Result so far: 139241.0
Deduct 545 from 773 and we're left with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

On to step 9:
545 can be fit into 2280 4 times, resulting in a remainder of 100.
Put 4 as the next digit of the answer. 
Result so far: 139241.4
The remainder is 100 after subtracting 2180 from 2280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 10:
When dividing 1000 by 545, we get 1 with a remainder of 455.
The number 1 becomes the next digit in our result. 
Result so far: 139241.41
Subtract 545 from 1000 to get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Advancing to step 11:
When dividing 4550 by 545, we get 8 with a remainder of 190.
Put 8 as the next digit of the answer. 
Result so far: 139241.418
If we subtract 4360 from 4550, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 12:
545 can be fit into 1900 3 times, resulting in a remainder of 265.
Record the quotient 3 as the next digit in the result. 
Result so far: 139241.4183
Deduct 1635 from 1900 and we're left with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Going ahead to step 13:
545 can be fit into 2650 4 times, resulting in a remainder of 470.
Use 4 as the next digit of our solution. 
Result so far: 139241.41834
If we subtract 2180 from 2650, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Step 14:
545 can be fit into 4700 8 times, resulting in a remainder of 340.
Record the quotient 8 as the next digit in the result. 
Result so far: 139241.418348
If we take 4360 away from 4700, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 15:
3400 divided by 545 is 6 with a remainder of 130.
The next digit of our result is 6. 
Result so far: 139241.4183486
If we subtract 3270 from 3400, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 16:
545 goes into 1300 2 times with a remainder of 210.
Record the quotient 2 as the next digit in the result. 
Result so far: 139241.41834862
Subtracting 1090 from 1300 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

In conclusion, the division gives 139241.41834862 with a balance of 2.1e-07.
