We divide 39686973 by 615
We're looking to find how many times 615 goes into 39686973.

Advancing to step 1:
3 divided by 615 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 615

Going ahead to step 2:
615 can be fit into 39 0 times, resulting in a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Fetch the next digit (6) from the dividend, attach it to 39 and continue: 396 / 615

Let's proceed to step 3:
When dividing 396 by 615, we get 0 with a remainder of 396.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 396 leaves us with 396.
Grab the next digit (8) from the dividend, add it to 396, then carry on: 3968 / 615

Let's proceed to step 4:
615 can be fit into 3968 6 times, resulting in a remainder of 278.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 3690 from 3968 to get 278.
Take the next digit (6) from the dividend and append it to 278, then repeat: 2786 / 615

Let's proceed to step 5:
615 goes into 2786 4 times with a remainder of 326.
Use 4 as the next digit of our solution. 
Result so far: 64.0
Subtract 2460 from 2786 to get 326.
Take the next digit (9) from the dividend and append it to 326, then repeat: 3269 / 615

Moving on to step 6:
When dividing 3269 by 615, we get 5 with a remainder of 194.
Use 5 as the next digit of our solution. 
Result so far: 645.0
If we subtract 3075 from 3269, we get 194.
Append the next digit (7) from the dividend to 194 and continue with: 1947 / 615

Step 7:
615 goes into 1947 3 times with a remainder of 102.
Put 3 as the next digit of the answer. 
Result so far: 6453.0
Deduct 1845 from 1947 and we're left with 102.
Include the next digit (3) from the dividend after 102, then repeat: 1023 / 615

Step 8:
The number 615 fits into 1023 1 times, leaving a remainder of 408.
Put 1 as the next digit of the answer. 
Result so far: 64531.0
Subtract 615 from 1023 to get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Step 9:
When dividing 4080 by 615, we get 6 with a remainder of 390.
Record the quotient 6 as the next digit in the result. 
Result so far: 64531.6
The remainder is 390 after subtracting 3690 from 4080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 10:
If we divide 3900 by 615, we get 6 and a remainder of 210.
The next digit of our result is 6. 
Result so far: 64531.66
Subtract 3690 from 3900 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

The quotient of the division is 64531.66, and the remainder is 0.21.
