53149612 ÷ 615 
We want to figure out the number of times 53149612 can be divided by 615.

Step 1:
615 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 615

Step 2:
53 divided by 615 is 0 with a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Bring next digit (1) of the dividend behind the 53 and repeat the process: 531 / 615

Advancing to step 3:
If we divide 531 by 615, we get 0 and a remainder of 531.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 531 after subtracting 0 from 531.
Take the next digit (4) from the dividend and append it to 531, then repeat: 5314 / 615

Moving on to step 4:
The number 615 fits into 5314 8 times, leaving a remainder of 394.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 4920 from 5314, we get 394.
Grab the next digit (9) from the dividend, add it to 394, then carry on: 3949 / 615

Going ahead to step 5:
If we divide 3949 by 615, we get 6 and a remainder of 259.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
If we take 3690 away from 3949, we end up with 259.
Bring next digit (6) of the dividend behind the 259 and repeat the process: 2596 / 615

Step 6:
615 goes into 2596 4 times with a remainder of 136.
Put 4 as the next digit of the answer. 
Result so far: 864.0
Subtract 2460 from 2596 to get 136.
Bring next digit (1) of the dividend behind the 136 and repeat the process: 1361 / 615

Let's proceed to step 7:
The number 615 fits into 1361 2 times, leaving a remainder of 131.
The next digit of our result is 2. 
Result so far: 8642.0
The remainder is 131 after subtracting 1230 from 1361.
Grab the next digit (2) from the dividend, add it to 131, then carry on: 1312 / 615

Let's proceed to step 8:
When dividing 1312 by 615, we get 2 with a remainder of 82.
The number 2 becomes the next digit in our result. 
Result so far: 86422.0
Subtracting 1230 from 1312 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 9:
The number 615 fits into 820 1 times, leaving a remainder of 205.
Record the quotient 1 as the next digit in the result. 
Result so far: 86422.1
Subtracting 615 from 820 leaves us with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Let's proceed to step 10:
615 can be fit into 2050 3 times, resulting in a remainder of 205.
Put 3 as the next digit of the answer. 
Result so far: 86422.13
Subtract 1845 from 2050 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Going ahead to step 11:
2050 divided by 615 is 3 with a remainder of 205.
Use 3 as the next digit of our solution. 
Result so far: 86422.133
Deduct 1845 from 2050 and we're left with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

In conclusion, the division gives 86422.133 with a balance of 0.0205.
