We divide 103211 by 39
We want to divide 103211 by 39.

Advancing to step 1:
When dividing 1 by 39, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 39

Moving on to step 2:
39 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 39

Moving on to step 3:
When dividing 103 by 39, we get 2 with a remainder of 25.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 78 from 103 and we're left with 25.
Take the next digit (2) from the dividend and append it to 25, then repeat: 252 / 39

Advancing to step 4:
252 divided by 39 is 6 with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtract 234 from 252 to get 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 39

Let's proceed to step 5:
If we divide 181 by 39, we get 4 and a remainder of 25.
Write down 4 as next digit of the result. 
Result so far: 264.0
Deduct 156 from 181 and we're left with 25.
Append the next digit (1) from the dividend to 25 and continue with: 251 / 39

Moving on to step 6:
39 can be fit into 251 6 times, resulting in a remainder of 17.
Put 6 as the next digit of the answer. 
Result so far: 2646.0
The remainder is 17 after subtracting 234 from 251.
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 7:
The number 39 fits into 170 4 times, leaving a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 2646.4
The remainder is 14 after subtracting 156 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
140 divided by 39 is 3 with a remainder of 23.
The next digit of our result is 3. 
Result so far: 2646.43
Subtracting 117 from 140 leaves us 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.

Let's proceed to step 9:
39 goes into 230 5 times with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 2646.435
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.

Moving on to step 10:
39 can be fit into 350 8 times, resulting in a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 2646.4358
If we subtract 312 from 350, we 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.

Moving on to step 11:
39 can be fit into 380 9 times, resulting in a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 2646.43589
Subtract 351 from 380 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 12:
The number 39 fits into 290 7 times, leaving a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 2646.435897
Deduct 273 from 290 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 13:
170 divided by 39 is 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 2646.4358974
Subtract 156 from 170 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 14:
When dividing 140 by 39, we get 3 with a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 2646.43589743
Subtract 117 from 140 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final outcome is 2646.43589743, with a leftover of 2.3e-08.
