31113941 ÷ 615 
We want to figure out the number of times 31113941 can be divided by 615.

Let's proceed to step 1:
615 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 615

On to step 2:
615 goes into 31 0 times with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Grab the next digit (1) from the dividend, add it to 31, then carry on: 311 / 615

Advancing to step 3:
615 goes into 311 0 times with a remainder of 311.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 311 after subtracting 0 from 311.
Bring next digit (1) of the dividend behind the 311 and repeat the process: 3111 / 615

Advancing to step 4:
615 can be fit into 3111 5 times, resulting in a remainder of 36.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 3075 from 3111 and we're left with 36.
Bring next digit (3) of the dividend behind the 36 and repeat the process: 363 / 615

Step 5:
615 can be fit into 363 0 times, resulting in a remainder of 363.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Subtract 0 from 363 to get 363.
Bring next digit (9) of the dividend behind the 363 and repeat the process: 3639 / 615

Let's proceed to step 6:
When dividing 3639 by 615, we get 5 with a remainder of 564.
Write down 5 as next digit of the result. 
Result so far: 505.0
If we take 3075 away from 3639, we end up with 564.
Bring next digit (4) of the dividend behind the 564 and repeat the process: 5644 / 615

Step 7:
If we divide 5644 by 615, we get 9 and a remainder of 109.
Record the quotient 9 as the next digit in the result. 
Result so far: 5059.0
If we subtract 5535 from 5644, we get 109.
Bring next digit (1) of the dividend behind the 109 and repeat the process: 1091 / 615

Let's proceed to step 8:
615 can be fit into 1091 1 times, resulting in a remainder of 476.
Write down 1 as next digit of the result. 
Result so far: 50591.0
Subtracting 615 from 1091 leaves us with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

On to step 9:
The number 615 fits into 4760 7 times, leaving a remainder of 455.
Record the quotient 7 as the next digit in the result. 
Result so far: 50591.7
Subtract 4305 from 4760 to get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Let's proceed to step 10:
615 can be fit into 4550 7 times, resulting in a remainder of 245.
The number 7 becomes the next digit in our result. 
Result so far: 50591.77
Subtract 4305 from 4550 to get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

The final result is 50591.77 with a remainder of 0.245.
