We look at the division of 428953 by 39 
We're looking to find how many times 39 goes into 428953.

Advancing to step 1:
If we divide 4 by 39, we get 0 and 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.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 39

Let's proceed to step 2:
When dividing 42 by 39, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 39 from 42 to get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 39

Step 3:
The number 39 fits into 38 0 times, leaving a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 38, we get 38.
Grab the next digit (9) from the dividend, add it to 38, then carry on: 389 / 39

Advancing to step 4:
When dividing 389 by 39, we get 9 with a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 109.0
The remainder is 38 after subtracting 351 from 389.
Include the next digit (5) from the dividend after 38, then repeat: 385 / 39

Let's proceed to step 5:
385 divided by 39 is 9 with a remainder of 34.
Record the quotient 9 as the next digit in the result. 
Result so far: 1099.0
Deduct 351 from 385 and we're left with 34.
Append the next digit (3) from the dividend to 34 and continue with: 343 / 39

Advancing to step 6:
The number 39 fits into 343 8 times, leaving a remainder of 31.
Put 8 as the next digit of the answer. 
Result so far: 10998.0
The remainder is 31 after subtracting 312 from 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
39 goes into 310 7 times with a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 10998.7
Subtract 273 from 310 to get 37.
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 8:
39 can be fit into 370 9 times, resulting in a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 10998.79
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.

Let's proceed to step 9:
The number 39 fits into 190 4 times, leaving a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 10998.794
If we subtract 156 from 190, 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.

Going ahead to step 10:
If we divide 340 by 39, we get 8 and a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 10998.7948
If we subtract 312 from 340, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 11:
39 can be fit into 280 7 times, resulting in a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 10998.79487
Deduct 273 from 280 and we're left 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 12:
39 goes into 70 1 times with a remainder of 31.
The next digit of our result is 1. 
Result so far: 10998.794871
Subtract 39 from 70 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 13:
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: 10998.7948717
Deduct 273 from 310 and we're left 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.

Going ahead to step 14:
370 divided by 39 is 9 with a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 10998.79487179
Subtracting 351 from 370 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 10998.79487179, with a leftover of 1.9e-08.
