Let's divide 13721080 by 215
We're looking to find how many times 215 goes into 13721080.

Advancing to step 1:
215 can be fit into 1 0 times, resulting in 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.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 215

On to step 2:
13 divided by 215 is 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 215

Advancing to step 3:
137 divided by 215 is 0 with a remainder of 137.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 137 to get 137.
Take the next digit (2) from the dividend and append it to 137, then repeat: 1372 / 215

Let's proceed to step 4:
If we divide 1372 by 215, we get 6 and a remainder of 82.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 82 after subtracting 1290 from 1372.
Bring next digit (1) of the dividend behind the 82 and repeat the process: 821 / 215

Going ahead to step 5:
If we divide 821 by 215, we get 3 and a remainder of 176.
Put 3 as the next digit of the answer. 
Result so far: 63.0
If we take 645 away from 821, we end up with 176.
Bring next digit (0) of the dividend behind the 176 and repeat the process: 1760 / 215

Advancing to step 6:
When dividing 1760 by 215, we get 8 with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 638.0
Subtract 1720 from 1760 to get 40.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 215

Moving on to step 7:
408 divided by 215 is 1 with a remainder of 193.
Put 1 as the next digit of the answer. 
Result so far: 6381.0
Deduct 215 from 408 and we're left with 193.
Grab the next digit (0) from the dividend, add it to 193, then carry on: 1930 / 215

Moving on to step 8:
When dividing 1930 by 215, we get 8 with a remainder of 210.
Put 8 as the next digit of the answer. 
Result so far: 63818.0
Subtracting 1720 from 1930 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 9:
215 goes into 2100 9 times with a remainder of 165.
Record the quotient 9 as the next digit in the result. 
Result so far: 63818.9
If we take 1935 away from 2100, we end up with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Moving on to step 10:
1650 divided by 215 is 7 with a remainder of 145.
The next digit of our result is 7. 
Result so far: 63818.97
Deduct 1505 from 1650 and we're left with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Going ahead to step 11:
If we divide 1450 by 215, we get 6 and a remainder of 160.
The next digit of our result is 6. 
Result so far: 63818.976
If we take 1290 away from 1450, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 12:
If we divide 1600 by 215, we get 7 and a remainder of 95.
Put 7 as the next digit of the answer. 
Result so far: 63818.9767
If we subtract 1505 from 1600, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 13:
The number 215 fits into 950 4 times, leaving a remainder of 90.
Use 4 as the next digit of our solution. 
Result so far: 63818.97674
If we subtract 860 from 950, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 14:
If we divide 900 by 215, we get 4 and a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 63818.976744
Subtracting 860 from 900 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 63818.976744, with a leftover of 4e-06.
