15709079 ÷ 615 
We're looking to find how many times 615 goes into 15709079.

Step 1:
615 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 615

Step 2:
15 divided by 615 is 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 615

Moving on to step 3:
615 goes into 157 0 times with a remainder of 157.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 157 and we're left with 157.
Bring next digit (0) of the dividend behind the 157 and repeat the process: 1570 / 615

On to step 4:
615 can be fit into 1570 2 times, resulting in a remainder of 340.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 1230 from 1570 leaves us with 340.
Grab the next digit (9) from the dividend, add it to 340, then carry on: 3409 / 615

Going ahead to step 5:
The number 615 fits into 3409 5 times, leaving a remainder of 334.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtracting 3075 from 3409 leaves us with 334.
Take the next digit (0) from the dividend and append it to 334, then repeat: 3340 / 615

Advancing to step 6:
615 can be fit into 3340 5 times, resulting in a remainder of 265.
Put 5 as the next digit of the answer. 
Result so far: 255.0
If we take 3075 away from 3340, we end up with 265.
Fetch the next digit (7) from the dividend, attach it to 265 and continue: 2657 / 615

On to step 7:
The number 615 fits into 2657 4 times, leaving a remainder of 197.
Use 4 as the next digit of our solution. 
Result so far: 2554.0
Deduct 2460 from 2657 and we're left with 197.
Take the next digit (9) from the dividend and append it to 197, then repeat: 1979 / 615

Step 8:
1979 divided by 615 is 3 with a remainder of 134.
Put 3 as the next digit of the answer. 
Result so far: 25543.0
Subtract 1845 from 1979 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Moving on to step 9:
615 goes into 1340 2 times with a remainder of 110.
The number 2 becomes the next digit in our result. 
Result so far: 25543.2
If we subtract 1230 from 1340, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 10:
1100 divided by 615 is 1 with a remainder of 485.
Write down 1 as next digit of the result. 
Result so far: 25543.21
The remainder is 485 after subtracting 615 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Let's proceed to step 11:
4850 divided by 615 is 7 with a remainder of 545.
Record the quotient 7 as the next digit in the result. 
Result so far: 25543.217
If we subtract 4305 from 4850, we get 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Step 12:
5450 divided by 615 is 8 with a remainder of 530.
Record the quotient 8 as the next digit in the result. 
Result so far: 25543.2178
Subtracting 4920 from 5450 leaves us with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Moving on to step 13:
615 goes into 5300 8 times with a remainder of 380.
Write down 8 as next digit of the result. 
Result so far: 25543.21788
The remainder is 380 after subtracting 4920 from 5300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

The final result is 25543.21788 with a remainder of 0.00038.
