Let's divide 31890695 by 140
The aim is to understand the frequency of 140 in 31890695.

On to step 1:
The number 140 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 140

Step 2:
The number 140 fits into 31 0 times, leaving a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Include the next digit (8) from the dividend after 31, then repeat: 318 / 140

Going ahead to step 3:
140 can be fit into 318 2 times, resulting in a remainder of 38.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 38 after subtracting 280 from 318.
Include the next digit (9) from the dividend after 38, then repeat: 389 / 140

On to step 4:
140 goes into 389 2 times with a remainder of 109.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we take 280 away from 389, we end up with 109.
Bring next digit (0) of the dividend behind the 109 and repeat the process: 1090 / 140

Advancing to step 5:
If we divide 1090 by 140, we get 7 and a remainder of 110.
Record the quotient 7 as the next digit in the result. 
Result so far: 227.0
If we take 980 away from 1090, we end up with 110.
Fetch the next digit (6) from the dividend, attach it to 110 and continue: 1106 / 140

On to step 6:
140 can be fit into 1106 7 times, resulting in a remainder of 126.
The number 7 becomes the next digit in our result. 
Result so far: 2277.0
Deduct 980 from 1106 and we're left with 126.
Bring next digit (9) of the dividend behind the 126 and repeat the process: 1269 / 140

Moving on to step 7:
If we divide 1269 by 140, we get 9 and a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 22779.0
Subtract 1260 from 1269 to get 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 140

Step 8:
95 divided by 140 is 0 with a remainder of 95.
Put 0 as the next digit of the answer. 
Result so far: 227790.0
Subtracting 0 from 95 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 9:
The number 140 fits into 950 6 times, leaving a remainder of 110.
Record the quotient 6 as the next digit in the result. 
Result so far: 227790.6
If we take 840 away from 950, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 10:
140 can be fit into 1100 7 times, resulting in a remainder of 120.
Write down 7 as next digit of the result. 
Result so far: 227790.67
The remainder is 120 after subtracting 980 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 11:
140 goes into 1200 8 times with a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 227790.678
Subtract 1120 from 1200 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 12:
If we divide 800 by 140, we get 5 and a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 227790.6785
Subtract 700 from 800 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 13:
If we divide 1000 by 140, we get 7 and a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 227790.67857
Deduct 980 from 1000 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 14:
The number 140 fits into 200 1 times, leaving a remainder of 60.
Record the quotient 1 as the next digit in the result. 
Result so far: 227790.678571
Subtracting 140 from 200 leaves us 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 15:
600 divided by 140 is 4 with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 227790.6785714
Subtracting 560 from 600 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 16:
When dividing 400 by 140, we get 2 with a remainder of 120.
Use 2 as the next digit of our solution. 
Result so far: 227790.67857142
Subtract 280 from 400 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The quotient of the division is 227790.67857142, and the remainder is 1.2e-07.
