We're dividing 76647019 by 486 
The aim is to understand the frequency of 486 in 76647019.

Moving on to step 1:
486 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 486

Let's proceed to step 2:
If we divide 76 by 486, we get 0 and a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Include the next digit (6) from the dividend after 76, then repeat: 766 / 486

Moving on to step 3:
766 divided by 486 is 1 with a remainder of 280.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 486 from 766 leaves us with 280.
Bring next digit (4) of the dividend behind the 280 and repeat the process: 2804 / 486

Going ahead to step 4:
When dividing 2804 by 486, we get 5 with a remainder of 374.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 2430 from 2804, we get 374.
Take the next digit (7) from the dividend and append it to 374, then repeat: 3747 / 486

Going ahead to step 5:
486 goes into 3747 7 times with a remainder of 345.
Write down 7 as next digit of the result. 
Result so far: 157.0
Deduct 3402 from 3747 and we're left with 345.
Grab the next digit (0) from the dividend, add it to 345, then carry on: 3450 / 486

On to step 6:
The number 486 fits into 3450 7 times, leaving a remainder of 48.
Use 7 as the next digit of our solution. 
Result so far: 1577.0
If we take 3402 away from 3450, we end up with 48.
Take the next digit (1) from the dividend and append it to 48, then repeat: 481 / 486

On to step 7:
The number 486 fits into 481 0 times, leaving a remainder of 481.
Record the quotient 0 as the next digit in the result. 
Result so far: 15770.0
Subtract 0 from 481 to get 481.
Grab the next digit (9) from the dividend, add it to 481, then carry on: 4819 / 486

On to step 8:
486 can be fit into 4819 9 times, resulting in a remainder of 445.
Record the quotient 9 as the next digit in the result. 
Result so far: 157709.0
If we take 4374 away from 4819, we end up with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Advancing to step 9:
When dividing 4450 by 486, we get 9 with a remainder of 76.
Record the quotient 9 as the next digit in the result. 
Result so far: 157709.9
If we subtract 4374 from 4450, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 10:
If we divide 760 by 486, we get 1 and a remainder of 274.
Use 1 as the next digit of our solution. 
Result so far: 157709.91
Subtract 486 from 760 to get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Moving on to step 11:
The number 486 fits into 2740 5 times, leaving a remainder of 310.
The number 5 becomes the next digit in our result. 
Result so far: 157709.915
The remainder is 310 after subtracting 2430 from 2740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 12:
486 can be fit into 3100 6 times, resulting in a remainder of 184.
Use 6 as the next digit of our solution. 
Result so far: 157709.9156
If we subtract 2916 from 3100, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 13:
When dividing 1840 by 486, we get 3 with a remainder of 382.
Record the quotient 3 as the next digit in the result. 
Result so far: 157709.91563
If we take 1458 away from 1840, we end up with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Moving on to step 14:
The number 486 fits into 3820 7 times, leaving a remainder of 418.
Record the quotient 7 as the next digit in the result. 
Result so far: 157709.915637
Subtracting 3402 from 3820 leaves us with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Moving on to step 15:
If we divide 4180 by 486, we get 8 and a remainder of 292.
The number 8 becomes the next digit in our result. 
Result so far: 157709.9156378
If we take 3888 away from 4180, we end up with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Moving on to step 16:
The number 486 fits into 2920 6 times, leaving a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 157709.91563786
Deduct 2916 from 2920 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 157709.91563786 with a remainder of 4e-09.
