We look at the division of 1973090 by 161 
Our goal is to divide 1973090 by 161.

Let's proceed to step 1:
161 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 161

Going ahead to step 2:
161 can be fit into 19 0 times, resulting in a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Append the next digit (7) from the dividend to 19 and continue with: 197 / 161

Moving on to step 3:
The number 161 fits into 197 1 times, leaving a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 161 from 197 leaves us with 36.
Include the next digit (3) from the dividend after 36, then repeat: 363 / 161

On to step 4:
161 can be fit into 363 2 times, resulting in a remainder of 41.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 322 from 363, we get 41.
Include the next digit (0) from the dividend after 41, then repeat: 410 / 161

Step 5:
When dividing 410 by 161, we get 2 with a remainder of 88.
Use 2 as the next digit of our solution. 
Result so far: 122.0
If we subtract 322 from 410, we get 88.
Take the next digit (9) from the dividend and append it to 88, then repeat: 889 / 161

Let's proceed to step 6:
When dividing 889 by 161, we get 5 with a remainder of 84.
The number 5 becomes the next digit in our result. 
Result so far: 1225.0
Deduct 805 from 889 and we're left with 84.
Include the next digit (0) from the dividend after 84, then repeat: 840 / 161

Moving on to step 7:
The number 161 fits into 840 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 12255.0
The remainder is 35 after subtracting 805 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 8:
When dividing 350 by 161, we get 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 12255.2
Deduct 322 from 350 and we're left 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.

Moving on to step 9:
161 can be fit into 280 1 times, resulting in a remainder of 119.
Put 1 as the next digit of the answer. 
Result so far: 12255.21
If we subtract 161 from 280, we get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Step 10:
When dividing 1190 by 161, we get 7 with a remainder of 63.
Put 7 as the next digit of the answer. 
Result so far: 12255.217
Subtract 1127 from 1190 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 11:
The number 161 fits into 630 3 times, leaving a remainder of 147.
Record the quotient 3 as the next digit in the result. 
Result so far: 12255.2173
If we take 483 away from 630, we end up with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Step 12:
The number 161 fits into 1470 9 times, leaving a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 12255.21739
Deduct 1449 from 1470 and we're left with 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 13:
161 goes into 210 1 times with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 12255.217391
The remainder is 49 after subtracting 161 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 14:
490 divided by 161 is 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 12255.2173913
If we take 483 away from 490, we end up 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.

Let's proceed to step 15:
161 can be fit into 70 0 times, resulting in a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 12255.2173913
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

In conclusion, the division gives 12255.2173913 with a balance of 7e-08.
