We look at the division of 213157 by 39 
We want to figure out the number of times 213157 can be divided by 39.

Let's proceed to step 1:
39 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 39

Going ahead to step 2:
When dividing 21 by 39, we get 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 39

Moving on to step 3:
213 divided by 39 is 5 with a remainder of 18.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 195 away from 213, we end up with 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 39

Moving on to step 4:
If we divide 181 by 39, we get 4 and a remainder of 25.
The number 4 becomes the next digit in our result. 
Result so far: 54.0
If we take 156 away from 181, we end up with 25.
Bring next digit (5) of the dividend behind the 25 and repeat the process: 255 / 39

On to step 5:
If we divide 255 by 39, we get 6 and a remainder of 21.
Put 6 as the next digit of the answer. 
Result so far: 546.0
Subtract 234 from 255 to get 21.
Include the next digit (7) from the dividend after 21, then repeat: 217 / 39

Advancing to step 6:
39 goes into 217 5 times with a remainder of 22.
Put 5 as the next digit of the answer. 
Result so far: 5465.0
Subtract 195 from 217 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
220 divided by 39 is 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 5465.5
Subtract 195 from 220 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 8:
39 goes into 250 6 times with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 5465.56
If we subtract 234 from 250, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
39 can be fit into 160 4 times, resulting in a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 5465.564
Subtracting 156 from 160 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
39 can be fit into 40 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 5465.5641
Subtract 39 from 40 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 11:
If we divide 10 by 39, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 5465.5641
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
39 goes into 100 2 times with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 5465.564102
Subtracting 78 from 100 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 13:
39 goes into 220 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 5465.5641025
The remainder is 25 after subtracting 195 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 14:
If we divide 250 by 39, we get 6 and a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 5465.56410256
Subtracting 234 from 250 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 5465.56410256, with a leftover of 1.6e-08.
