We divide 161622 by 39
We want to figure out the number of times 161622 can be divided by 39.

Advancing to step 1:
If we divide 1 by 39, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 39

Let's proceed to step 2:
39 goes into 16 0 times with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 39

Advancing to step 3:
When dividing 161 by 39, we get 4 with a remainder of 5.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 156 from 161, we get 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 39

Advancing to step 4:
The number 39 fits into 56 1 times, leaving a remainder of 17.
The next digit of our result is 1. 
Result so far: 41.0
Subtract 39 from 56 to get 17.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 39

On to step 5:
172 divided by 39 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 414.0
Deduct 156 from 172 and we're left with 16.
Include the next digit (2) from the dividend after 16, then repeat: 162 / 39

On to step 6:
When dividing 162 by 39, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 4144.0
Deduct 156 from 162 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
If we divide 60 by 39, we get 1 and a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 4144.1
If we subtract 39 from 60, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 8:
The number 39 fits into 210 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 4144.15
The remainder is 15 after subtracting 195 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 9:
The number 39 fits into 150 3 times, leaving a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 4144.153
If we subtract 117 from 150, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 10:
If we divide 330 by 39, we get 8 and a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 4144.1538
Subtracting 312 from 330 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 11:
39 goes into 180 4 times with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 4144.15384
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
39 can be fit into 240 6 times, resulting in a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 4144.153846
If we take 234 away from 240, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
When dividing 60 by 39, we get 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 4144.1538461
Subtract 39 from 60 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 14:
When dividing 210 by 39, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 4144.15384615
Subtracting 195 from 210 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

In conclusion, the division gives 4144.15384615 with a balance of 1.5e-08.
