We're dividing 84521213 by 39 
We're looking to find how many times 39 goes into 84521213.

Going ahead to step 1:
If we divide 8 by 39, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 39

Step 2:
39 goes into 84 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 6 after subtracting 78 from 84.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 39

Advancing to step 3:
When dividing 65 by 39, we get 1 with a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we take 39 away from 65, we end up with 26.
Include the next digit (2) from the dividend after 26, then repeat: 262 / 39

Advancing to step 4:
The number 39 fits into 262 6 times, leaving a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 216.0
Subtracting 234 from 262 leaves us with 28.
Grab the next digit (1) from the dividend, add it to 28, then carry on: 281 / 39

On to step 5:
39 goes into 281 7 times with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 2167.0
Subtracting 273 from 281 leaves us with 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 39

Moving on to step 6:
39 goes into 82 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 21672.0
Deduct 78 from 82 and we're left with 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 39

Advancing to step 7:
41 divided by 39 is 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 216721.0
If we subtract 39 from 41, we get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 39

Advancing to step 8:
39 goes into 23 0 times with a remainder of 23.
The next digit of our result is 0. 
Result so far: 2167210.0
If we take 0 away from 23, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 9:
230 divided by 39 is 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 2167210.5
The remainder is 35 after subtracting 195 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 10:
If we divide 350 by 39, we get 8 and a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 2167210.58
Subtract 312 from 350 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 11:
The number 39 fits into 380 9 times, leaving a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 2167210.589
Subtracting 351 from 380 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 12:
290 divided by 39 is 7 with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 2167210.5897
If we subtract 273 from 290, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 13:
39 can be fit into 170 4 times, resulting in a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 2167210.58974
Subtracting 156 from 170 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 14:
39 can be fit into 140 3 times, resulting in a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 2167210.589743
Deduct 117 from 140 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 15:
39 can be fit into 230 5 times, resulting in a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 2167210.5897435
Deduct 195 from 230 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 16:
39 goes into 350 8 times with a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 2167210.58974358
The remainder is 38 after subtracting 312 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The quotient of the division is 2167210.58974358, and the remainder is 3.8e-08.
