73148197 ÷ 518 
We want to divide 73148197 by 518.

Advancing to step 1:
The number 518 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 518

Going ahead to step 2:
When dividing 73 by 518, we get 0 with a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Grab the next digit (1) from the dividend, add it to 73, then carry on: 731 / 518

Advancing to step 3:
When dividing 731 by 518, we get 1 with a remainder of 213.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 518 from 731, we get 213.
Include the next digit (4) from the dividend after 213, then repeat: 2134 / 518

Advancing to step 4:
2134 divided by 518 is 4 with a remainder of 62.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 2072 from 2134 leaves us with 62.
Take the next digit (8) from the dividend and append it to 62, then repeat: 628 / 518

Moving on to step 5:
If we divide 628 by 518, we get 1 and a remainder of 110.
Write down 1 as next digit of the result. 
Result so far: 141.0
Subtracting 518 from 628 leaves us with 110.
Fetch the next digit (1) from the dividend, attach it to 110 and continue: 1101 / 518

Step 6:
518 can be fit into 1101 2 times, resulting in a remainder of 65.
Record the quotient 2 as the next digit in the result. 
Result so far: 1412.0
If we take 1036 away from 1101, we end up with 65.
Fetch the next digit (9) from the dividend, attach it to 65 and continue: 659 / 518

Moving on to step 7:
If we divide 659 by 518, we get 1 and a remainder of 141.
The number 1 becomes the next digit in our result. 
Result so far: 14121.0
Deduct 518 from 659 and we're left with 141.
Fetch the next digit (7) from the dividend, attach it to 141 and continue: 1417 / 518

Advancing to step 8:
1417 divided by 518 is 2 with a remainder of 381.
Record the quotient 2 as the next digit in the result. 
Result so far: 141212.0
If we subtract 1036 from 1417, we get 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Let's proceed to step 9:
518 can be fit into 3810 7 times, resulting in a remainder of 184.
Write down 7 as next digit of the result. 
Result so far: 141212.7
If we take 3626 away from 3810, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 10:
518 goes into 1840 3 times with a remainder of 286.
Put 3 as the next digit of the answer. 
Result so far: 141212.73
Deduct 1554 from 1840 and we're left with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Going ahead to step 11:
518 goes into 2860 5 times with a remainder of 270.
The number 5 becomes the next digit in our result. 
Result so far: 141212.735
Subtracting 2590 from 2860 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 12:
When dividing 2700 by 518, we get 5 with a remainder of 110.
Use 5 as the next digit of our solution. 
Result so far: 141212.7355
Subtracting 2590 from 2700 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

After the division, we end up with 141212.7355 and a remainder of 0.0011.
