We look at the division of 33212169 by 407 
We're looking to find how many times 407 goes into 33212169.

Advancing to step 1:
When dividing 3 by 407, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 407

Let's proceed to step 2:
The number 407 fits into 33 0 times, leaving a remainder of 33.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 33, we end up with 33.
Grab the next digit (2) from the dividend, add it to 33, then carry on: 332 / 407

On to step 3:
332 divided by 407 is 0 with a remainder of 332.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 332 after subtracting 0 from 332.
Include the next digit (1) from the dividend after 332, then repeat: 3321 / 407

Step 4:
3321 divided by 407 is 8 with a remainder of 65.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 65 after subtracting 3256 from 3321.
Fetch the next digit (2) from the dividend, attach it to 65 and continue: 652 / 407

On to step 5:
407 can be fit into 652 1 times, resulting in a remainder of 245.
The next digit of our result is 1. 
Result so far: 81.0
The remainder is 245 after subtracting 407 from 652.
Grab the next digit (1) from the dividend, add it to 245, then carry on: 2451 / 407

Advancing to step 6:
2451 divided by 407 is 6 with a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 816.0
The remainder is 9 after subtracting 2442 from 2451.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 407

Going ahead to step 7:
If we divide 96 by 407, we get 0 and a remainder of 96.
The next digit of our result is 0. 
Result so far: 8160.0
The remainder is 96 after subtracting 0 from 96.
Take the next digit (9) from the dividend and append it to 96, then repeat: 969 / 407

Going ahead to step 8:
407 can be fit into 969 2 times, resulting in a remainder of 155.
Put 2 as the next digit of the answer. 
Result so far: 81602.0
The remainder is 155 after subtracting 814 from 969.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Advancing to step 9:
The number 407 fits into 1550 3 times, leaving a remainder of 329.
Record the quotient 3 as the next digit in the result. 
Result so far: 81602.3
Subtract 1221 from 1550 to get 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Moving on to step 10:
407 goes into 3290 8 times with a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 81602.38
If we subtract 3256 from 3290, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 11:
The number 407 fits into 340 0 times, leaving a remainder of 340.
Use 0 as the next digit of our solution. 
Result so far: 81602.38
If we take 0 away from 340, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 12:
3400 divided by 407 is 8 with a remainder of 144.
The next digit of our result is 8. 
Result so far: 81602.3808
If we take 3256 away from 3400, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 13:
If we divide 1440 by 407, we get 3 and a remainder of 219.
The next digit of our result is 3. 
Result so far: 81602.38083
Deduct 1221 from 1440 and we're left with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Step 14:
407 can be fit into 2190 5 times, resulting in a remainder of 155.
Put 5 as the next digit of the answer. 
Result so far: 81602.380835
Subtract 2035 from 2190 to get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Step 15:
1550 divided by 407 is 3 with a remainder of 329.
Record the quotient 3 as the next digit in the result. 
Result so far: 81602.3808353
Deduct 1221 from 1550 and we're left with 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Step 16:
3290 divided by 407 is 8 with a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 81602.38083538
Deduct 3256 from 3290 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 81602.38083538 and a remainder of 3.4e-08.
