Let's divide 31380736 by 161
We want to figure out the number of times 31380736 can be divided by 161.

Advancing to step 1:
161 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 161

Moving on to step 2:
If we divide 31 by 161, we get 0 and a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Grab the next digit (3) from the dividend, add it to 31, then carry on: 313 / 161

On to step 3:
313 divided by 161 is 1 with a remainder of 152.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 161 from 313, we get 152.
Append the next digit (8) from the dividend to 152 and continue with: 1528 / 161

On to step 4:
The number 161 fits into 1528 9 times, leaving a remainder of 79.
Put 9 as the next digit of the answer. 
Result so far: 19.0
The remainder is 79 after subtracting 1449 from 1528.
Bring next digit (0) of the dividend behind the 79 and repeat the process: 790 / 161

Advancing to step 5:
When dividing 790 by 161, we get 4 with a remainder of 146.
The number 4 becomes the next digit in our result. 
Result so far: 194.0
The remainder is 146 after subtracting 644 from 790.
Append the next digit (7) from the dividend to 146 and continue with: 1467 / 161

Going ahead to step 6:
161 can be fit into 1467 9 times, resulting in a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 1949.0
Subtracting 1449 from 1467 leaves us with 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 161

Going ahead to step 7:
The number 161 fits into 183 1 times, leaving a remainder of 22.
The next digit of our result is 1. 
Result so far: 19491.0
If we subtract 161 from 183, we get 22.
Append the next digit (6) from the dividend to 22 and continue with: 226 / 161

On to step 8:
When dividing 226 by 161, we get 1 with a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 194911.0
Subtracting 161 from 226 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 9:
The number 161 fits into 650 4 times, leaving a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 194911.4
If we take 644 away from 650, 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.

Going ahead to step 10:
The number 161 fits into 60 0 times, leaving a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 194911.4
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 11:
When dividing 600 by 161, we get 3 with a remainder of 117.
Put 3 as the next digit of the answer. 
Result so far: 194911.403
The remainder is 117 after subtracting 483 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Going ahead to step 12:
When dividing 1170 by 161, we get 7 with a remainder of 43.
The next digit of our result is 7. 
Result so far: 194911.4037
If we take 1127 away from 1170, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 13:
430 divided by 161 is 2 with a remainder of 108.
Write down 2 as next digit of the result. 
Result so far: 194911.40372
If we take 322 away from 430, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 14:
The number 161 fits into 1080 6 times, leaving a remainder of 114.
Record the quotient 6 as the next digit in the result. 
Result so far: 194911.403726
Subtract 966 from 1080 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 15:
If we divide 1140 by 161, we get 7 and a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 194911.4037267
The remainder is 13 after subtracting 1127 from 1140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 16:
161 can be fit into 130 0 times, resulting in a remainder of 130.
Put 0 as the next digit of the answer. 
Result so far: 194911.4037267
Subtracting 0 from 130 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

In conclusion, the division gives 194911.4037267 with a balance of 1.3e-07.
