84236912 ÷ 615 
Let's see how many times 615 fits into 84236912.

Going ahead to step 1:
When dividing 8 by 615, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 615

Moving on to step 2:
615 goes into 84 0 times with a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Grab the next digit (2) from the dividend, add it to 84, then carry on: 842 / 615

Going ahead to step 3:
615 can be fit into 842 1 times, resulting in a remainder of 227.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 615 from 842 and we're left with 227.
Bring next digit (3) of the dividend behind the 227 and repeat the process: 2273 / 615

Let's proceed to step 4:
615 goes into 2273 3 times with a remainder of 428.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 1845 from 2273, we get 428.
Bring next digit (6) of the dividend behind the 428 and repeat the process: 4286 / 615

On to step 5:
615 can be fit into 4286 6 times, resulting in a remainder of 596.
Record the quotient 6 as the next digit in the result. 
Result so far: 136.0
Subtract 3690 from 4286 to get 596.
Fetch the next digit (9) from the dividend, attach it to 596 and continue: 5969 / 615

On to step 6:
If we divide 5969 by 615, we get 9 and a remainder of 434.
The next digit of our result is 9. 
Result so far: 1369.0
Subtracting 5535 from 5969 leaves us with 434.
Take the next digit (1) from the dividend and append it to 434, then repeat: 4341 / 615

Let's proceed to step 7:
615 goes into 4341 7 times with a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 13697.0
The remainder is 36 after subtracting 4305 from 4341.
Append the next digit (2) from the dividend to 36 and continue with: 362 / 615

On to step 8:
615 can be fit into 362 0 times, resulting in a remainder of 362.
Record the quotient 0 as the next digit in the result. 
Result so far: 136970.0
If we take 0 away from 362, we end up with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Advancing to step 9:
The number 615 fits into 3620 5 times, leaving a remainder of 545.
Put 5 as the next digit of the answer. 
Result so far: 136970.5
Subtract 3075 from 3620 to 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.

Let's proceed to step 10:
The number 615 fits into 5450 8 times, leaving a remainder of 530.
The number 8 becomes the next digit in our result. 
Result so far: 136970.58
If we take 4920 away from 5450, we end up 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 11:
615 can be fit into 5300 8 times, resulting in a remainder of 380.
Write down 8 as next digit of the result. 
Result so far: 136970.588
If we take 4920 away from 5300, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Our division results in 136970.588 with a remaining 0.038.
