We divide 423820 by 39
We're looking to find how many times 39 goes into 423820.

On to step 1:
39 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 39

Let's proceed to step 2:
If we divide 42 by 39, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 3 after subtracting 39 from 42.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 39

Advancing to step 3:
33 divided by 39 is 0 with a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 33 leaves us with 33.
Take the next digit (8) from the dividend and append it to 33, then repeat: 338 / 39

Moving on to step 4:
39 can be fit into 338 8 times, resulting in a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 108.0
Deduct 312 from 338 and we're left with 26.
Grab the next digit (2) from the dividend, add it to 26, then carry on: 262 / 39

Let's proceed to step 5:
39 goes into 262 6 times with a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 1086.0
Deduct 234 from 262 and we're left with 28.
Fetch the next digit (0) from the dividend, attach it to 28 and continue: 280 / 39

Step 6:
If we divide 280 by 39, we get 7 and a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 10867.0
Subtracting 273 from 280 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
When dividing 70 by 39, we get 1 with a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 10867.1
Deduct 39 from 70 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 8:
39 can be fit into 310 7 times, resulting in a remainder of 37.
The next digit of our result is 7. 
Result so far: 10867.17
The remainder is 37 after subtracting 273 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 9:
39 can be fit into 370 9 times, resulting in a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 10867.179
Subtract 351 from 370 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 10:
39 can be fit into 190 4 times, resulting in a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 10867.1794
Deduct 156 from 190 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.

Advancing to step 11:
340 divided by 39 is 8 with a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 10867.17948
If we take 312 away from 340, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 12:
39 goes into 280 7 times with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 10867.179487
Subtracting 273 from 280 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 13:
When dividing 70 by 39, we get 1 with a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 10867.1794871
Deduct 39 from 70 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 14:
When dividing 310 by 39, we get 7 with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 10867.17948717
Subtracting 273 from 310 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

After the division, we end up with 10867.17948717 and a remainder of 3.7e-08.
