15665358 ÷ 212 
Let's see how many times 212 fits into 15665358.

Step 1:
212 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 212

Moving on to step 2:
If we divide 15 by 212, we get 0 and a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Bring next digit (6) of the dividend behind the 15 and repeat the process: 156 / 212

Moving on to step 3:
156 divided by 212 is 0 with a remainder of 156.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 156 and we're left with 156.
Bring next digit (6) of the dividend behind the 156 and repeat the process: 1566 / 212

Step 4:
If we divide 1566 by 212, we get 7 and a remainder of 82.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 1484 away from 1566, we end up with 82.
Take the next digit (5) from the dividend and append it to 82, then repeat: 825 / 212

Moving on to step 5:
When dividing 825 by 212, we get 3 with a remainder of 189.
The next digit of our result is 3. 
Result so far: 73.0
If we take 636 away from 825, we end up with 189.
Bring next digit (3) of the dividend behind the 189 and repeat the process: 1893 / 212

Let's proceed to step 6:
1893 divided by 212 is 8 with a remainder of 197.
Record the quotient 8 as the next digit in the result. 
Result so far: 738.0
If we take 1696 away from 1893, we end up with 197.
Take the next digit (5) from the dividend and append it to 197, then repeat: 1975 / 212

Let's proceed to step 7:
212 can be fit into 1975 9 times, resulting in a remainder of 67.
The next digit of our result is 9. 
Result so far: 7389.0
If we take 1908 away from 1975, we end up with 67.
Grab the next digit (8) from the dividend, add it to 67, then carry on: 678 / 212

Moving on to step 8:
The number 212 fits into 678 3 times, leaving a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 73893.0
Subtracting 636 from 678 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 9:
When dividing 420 by 212, we get 1 with a remainder of 208.
The next digit of our result is 1. 
Result so far: 73893.1
If we subtract 212 from 420, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 10:
When dividing 2080 by 212, we get 9 with a remainder of 172.
Write down 9 as next digit of the result. 
Result so far: 73893.19
Subtracting 1908 from 2080 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 11:
212 can be fit into 1720 8 times, resulting in a remainder of 24.
The next digit of our result is 8. 
Result so far: 73893.198
If we subtract 1696 from 1720, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 12:
212 can be fit into 240 1 times, resulting in a remainder of 28.
The next digit of our result is 1. 
Result so far: 73893.1981
If we subtract 212 from 240, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 13:
280 divided by 212 is 1 with a remainder of 68.
Record the quotient 1 as the next digit in the result. 
Result so far: 73893.19811
If we subtract 212 from 280, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final result is 73893.19811 with a remainder of 6.8e-05.
