We divide 435198 by 31
The aim is to understand the frequency of 31 in 435198.

Step 1:
If we divide 4 by 31, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 31

Step 2:
43 divided by 31 is 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 31 from 43 to get 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 31

Step 3:
If we divide 125 by 31, we get 4 and a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 124 from 125 and we're left with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 31

Moving on to step 4:
31 goes into 11 0 times with a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 140.0
Deduct 0 from 11 and we're left with 11.
Grab the next digit (9) from the dividend, add it to 11, then carry on: 119 / 31

Advancing to step 5:
31 goes into 119 3 times with a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 1403.0
Deduct 93 from 119 and we're left with 26.
Append the next digit (8) from the dividend to 26 and continue with: 268 / 31

Let's proceed to step 6:
When dividing 268 by 31, we get 8 with a remainder of 20.
The next digit of our result is 8. 
Result so far: 14038.0
The remainder is 20 after subtracting 248 from 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
31 goes into 200 6 times with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 14038.6
The remainder is 14 after subtracting 186 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
The number 31 fits into 140 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 14038.64
Subtract 124 from 140 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
If we divide 160 by 31, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 14038.645
Deduct 155 from 160 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 10:
The number 31 fits into 50 1 times, leaving a remainder of 19.
The next digit of our result is 1. 
Result so far: 14038.6451
The remainder is 19 after subtracting 31 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 11:
31 can be fit into 190 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 14038.64516
Subtract 186 from 190 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
31 can be fit into 40 1 times, resulting in a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 14038.645161
Subtract 31 from 40 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 13:
The number 31 fits into 90 2 times, leaving a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 14038.6451612
If we take 62 away from 90, we end up 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 14:
When dividing 280 by 31, we get 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 14038.64516129
If we take 279 away from 280, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 14038.64516129, and the remainder is 1e-09.
