15571638 divided by 215 
We want to divide 15571638 by 215.

Advancing to step 1:
The number 215 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 215

Let's proceed to step 2:
If we divide 15 by 215, we get 0 and a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 215

Advancing to step 3:
215 can be fit into 155 0 times, resulting in a remainder of 155.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 155 after subtracting 0 from 155.
Grab the next digit (7) from the dividend, add it to 155, then carry on: 1557 / 215

Moving on to step 4:
When dividing 1557 by 215, we get 7 with a remainder of 52.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 1505 from 1557 to get 52.
Include the next digit (1) from the dividend after 52, then repeat: 521 / 215

Advancing to step 5:
If we divide 521 by 215, we get 2 and a remainder of 91.
Use 2 as the next digit of our solution. 
Result so far: 72.0
Subtract 430 from 521 to get 91.
Include the next digit (6) from the dividend after 91, then repeat: 916 / 215

Advancing to step 6:
If we divide 916 by 215, we get 4 and a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 724.0
Deduct 860 from 916 and we're left with 56.
Fetch the next digit (3) from the dividend, attach it to 56 and continue: 563 / 215

Advancing to step 7:
When dividing 563 by 215, we get 2 with a remainder of 133.
The next digit of our result is 2. 
Result so far: 7242.0
If we subtract 430 from 563, we get 133.
Bring next digit (8) of the dividend behind the 133 and repeat the process: 1338 / 215

On to step 8:
When dividing 1338 by 215, we get 6 with a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 72426.0
Subtract 1290 from 1338 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
When dividing 480 by 215, we get 2 with a remainder of 50.
Write down 2 as next digit of the result. 
Result so far: 72426.2
Deduct 430 from 480 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
215 can be fit into 500 2 times, resulting in a remainder of 70.
Record the quotient 2 as the next digit in the result. 
Result so far: 72426.22
Subtract 430 from 500 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 72426.22 with a remainder of 0.07.
