49901663 ÷ 615 
We want to divide 49901663 by 615.

Let's proceed to step 1:
The number 615 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 615

Moving on to step 2:
615 goes into 49 0 times with a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 49, we end up with 49.
Take the next digit (9) from the dividend and append it to 49, then repeat: 499 / 615

Going ahead to step 3:
If we divide 499 by 615, we get 0 and a remainder of 499.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 499 and we're left with 499.
Append the next digit (0) from the dividend to 499 and continue with: 4990 / 615

On to step 4:
4990 divided by 615 is 8 with a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 4920 from 4990 leaves us with 70.
Include the next digit (1) from the dividend after 70, then repeat: 701 / 615

Step 5:
The number 615 fits into 701 1 times, leaving a remainder of 86.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
If we take 615 away from 701, we end up with 86.
Take the next digit (6) from the dividend and append it to 86, then repeat: 866 / 615

Step 6:
When dividing 866 by 615, we get 1 with a remainder of 251.
The next digit of our result is 1. 
Result so far: 811.0
Subtracting 615 from 866 leaves us with 251.
Take the next digit (6) from the dividend and append it to 251, then repeat: 2516 / 615

Advancing to step 7:
615 can be fit into 2516 4 times, resulting in a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 8114.0
Deduct 2460 from 2516 and we're left with 56.
Grab the next digit (3) from the dividend, add it to 56, then carry on: 563 / 615

Advancing to step 8:
If we divide 563 by 615, we get 0 and a remainder of 563.
Write down 0 as next digit of the result. 
Result so far: 81140.0
The remainder is 563 after subtracting 0 from 563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

Advancing to step 9:
615 goes into 5630 9 times with a remainder of 95.
Record the quotient 9 as the next digit in the result. 
Result so far: 81140.9
The remainder is 95 after subtracting 5535 from 5630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Let's proceed to step 10:
If we divide 950 by 615, we get 1 and a remainder of 335.
Use 1 as the next digit of our solution. 
Result so far: 81140.91
Subtract 615 from 950 to get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

On to step 11:
3350 divided by 615 is 5 with a remainder of 275.
Use 5 as the next digit of our solution. 
Result so far: 81140.915
Deduct 3075 from 3350 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Advancing to step 12:
615 can be fit into 2750 4 times, resulting in a remainder of 290.
Record the quotient 4 as the next digit in the result. 
Result so far: 81140.9154
Subtract 2460 from 2750 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 13:
2900 divided by 615 is 4 with a remainder of 440.
Use 4 as the next digit of our solution. 
Result so far: 81140.91544
Subtracting 2460 from 2900 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

The final result is 81140.91544 with a remainder of 0.00044.
