Let's divide 31249439 by 486
The aim is to understand the frequency of 486 in 31249439.

Let's proceed to step 1:
3 divided by 486 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 486

On to step 2:
486 goes into 31 0 times with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Take the next digit (2) from the dividend and append it to 31, then repeat: 312 / 486

On to step 3:
The number 486 fits into 312 0 times, leaving a remainder of 312.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 312 leaves us with 312.
Append the next digit (4) from the dividend to 312 and continue with: 3124 / 486

Step 4:
When dividing 3124 by 486, we get 6 with a remainder of 208.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 2916 from 3124, we get 208.
Bring next digit (9) of the dividend behind the 208 and repeat the process: 2089 / 486

Advancing to step 5:
If we divide 2089 by 486, we get 4 and a remainder of 145.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
The remainder is 145 after subtracting 1944 from 2089.
Take the next digit (4) from the dividend and append it to 145, then repeat: 1454 / 486

Moving on to step 6:
The number 486 fits into 1454 2 times, leaving a remainder of 482.
The number 2 becomes the next digit in our result. 
Result so far: 642.0
Subtract 972 from 1454 to get 482.
Append the next digit (3) from the dividend to 482 and continue with: 4823 / 486

Advancing to step 7:
When dividing 4823 by 486, we get 9 with a remainder of 449.
The next digit of our result is 9. 
Result so far: 6429.0
Deduct 4374 from 4823 and we're left with 449.
Grab the next digit (9) from the dividend, add it to 449, then carry on: 4499 / 486

Let's proceed to step 8:
When dividing 4499 by 486, we get 9 with a remainder of 125.
The number 9 becomes the next digit in our result. 
Result so far: 64299.0
If we take 4374 away from 4499, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 9:
486 can be fit into 1250 2 times, resulting in a remainder of 278.
Write down 2 as next digit of the result. 
Result so far: 64299.2
If we subtract 972 from 1250, we get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Going ahead to step 10:
The number 486 fits into 2780 5 times, leaving a remainder of 350.
Put 5 as the next digit of the answer. 
Result so far: 64299.25
Subtract 2430 from 2780 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 11:
486 goes into 3500 7 times with a remainder of 98.
Write down 7 as next digit of the result. 
Result so far: 64299.257
Subtracting 3402 from 3500 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 12:
486 can be fit into 980 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 64299.2572
Deduct 972 from 980 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
80 divided by 486 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 64299.2572
Subtract 0 from 80 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.

Let's proceed to step 14:
486 goes into 800 1 times with a remainder of 314.
Put 1 as the next digit of the answer. 
Result so far: 64299.257201
Subtract 486 from 800 to get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Advancing to step 15:
486 can be fit into 3140 6 times, resulting in a remainder of 224.
Put 6 as the next digit of the answer. 
Result so far: 64299.2572016
Subtracting 2916 from 3140 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 16:
2240 divided by 486 is 4 with a remainder of 296.
Record the quotient 4 as the next digit in the result. 
Result so far: 64299.25720164
Subtract 1944 from 2240 to get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

After the division, we end up with 64299.25720164 and a remainder of 2.96e-07.
