Let's divide 84642 by 39
Our goal is to divide 84642 by 39.

Step 1:
39 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 39

On to step 2:
The number 39 fits into 84 2 times, leaving a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 78 from 84, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 39

Advancing to step 3:
The number 39 fits into 66 1 times, leaving a remainder of 27.
The next digit of our result is 1. 
Result so far: 21.0
Subtract 39 from 66 to get 27.
Grab the next digit (4) from the dividend, add it to 27, then carry on: 274 / 39

Let's proceed to step 4:
39 can be fit into 274 7 times, resulting in a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 217.0
Deduct 273 from 274 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 39

Going ahead to step 5:
When dividing 12 by 39, we get 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 2170.0
If we take 0 away from 12, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 6:
120 divided by 39 is 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 2170.3
If we take 117 away from 120, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
39 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 2170.3
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
When dividing 300 by 39, we get 7 with a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 2170.307
If we take 273 away from 300, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 9:
270 divided by 39 is 6 with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 2170.3076
Subtracting 234 from 270 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 10:
The number 39 fits into 360 9 times, leaving a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 2170.30769
Subtracting 351 from 360 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 11:
39 can be fit into 90 2 times, resulting in a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 2170.307692
Subtracting 78 from 90 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
If we divide 120 by 39, we get 3 and a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 2170.3076923
Deduct 117 from 120 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 13:
39 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 2170.3076923
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 2170.3076923, and the remainder is 3e-08.
