39139210 ÷ 212 
We're looking to find how many times 212 goes into 39139210.

Going ahead to step 1:
The number 212 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 212

Going ahead to step 2:
212 can be fit into 39 0 times, resulting in a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Append the next digit (1) from the dividend to 39 and continue with: 391 / 212

Step 3:
212 can be fit into 391 1 times, resulting in a remainder of 179.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 212 from 391 leaves us with 179.
Bring next digit (3) of the dividend behind the 179 and repeat the process: 1793 / 212

Step 4:
The number 212 fits into 1793 8 times, leaving a remainder of 97.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtract 1696 from 1793 to get 97.
Append the next digit (9) from the dividend to 97 and continue with: 979 / 212

On to step 5:
The number 212 fits into 979 4 times, leaving a remainder of 131.
Write down 4 as next digit of the result. 
Result so far: 184.0
Subtract 848 from 979 to get 131.
Bring next digit (2) of the dividend behind the 131 and repeat the process: 1312 / 212

Moving on to step 6:
If we divide 1312 by 212, we get 6 and a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 1846.0
Deduct 1272 from 1312 and we're left with 40.
Fetch the next digit (1) from the dividend, attach it to 40 and continue: 401 / 212

Moving on to step 7:
401 divided by 212 is 1 with a remainder of 189.
Use 1 as the next digit of our solution. 
Result so far: 18461.0
Deduct 212 from 401 and we're left with 189.
Take the next digit (0) from the dividend and append it to 189, then repeat: 1890 / 212

Going ahead to step 8:
1890 divided by 212 is 8 with a remainder of 194.
Record the quotient 8 as the next digit in the result. 
Result so far: 184618.0
The remainder is 194 after subtracting 1696 from 1890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Moving on to step 9:
1940 divided by 212 is 9 with a remainder of 32.
Put 9 as the next digit of the answer. 
Result so far: 184618.9
Subtracting 1908 from 1940 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 10:
212 can be fit into 320 1 times, resulting in a remainder of 108.
The next digit of our result is 1. 
Result so far: 184618.91
Deduct 212 from 320 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 11:
212 can be fit into 1080 5 times, resulting in a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 184618.915
If we take 1060 away from 1080, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
When dividing 200 by 212, we get 0 with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 184618.915
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 13:
212 goes into 2000 9 times with a remainder of 92.
Put 9 as the next digit of the answer. 
Result so far: 184618.91509
Deduct 1908 from 2000 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 14:
When dividing 920 by 212, we get 4 with a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 184618.915094
The remainder is 72 after subtracting 848 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 15:
The number 212 fits into 720 3 times, leaving a remainder of 84.
Write down 3 as next digit of the result. 
Result so far: 184618.9150943
If we subtract 636 from 720, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 16:
If we divide 840 by 212, we get 3 and a remainder of 204.
Write down 3 as next digit of the result. 
Result so far: 184618.91509433
Subtracting 636 from 840 leaves us with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

After the division, we end up with 184618.91509433 and a remainder of 2.04e-07.
