83070123 ÷ 654 
The aim is to understand the frequency of 654 in 83070123.

Moving on to step 1:
654 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 654

On to step 2:
When dividing 83 by 654, we get 0 with a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 83 and we're left with 83.
Append the next digit (0) from the dividend to 83 and continue with: 830 / 654

On to step 3:
When dividing 830 by 654, we get 1 with a remainder of 176.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 176 after subtracting 654 from 830.
Take the next digit (7) from the dividend and append it to 176, then repeat: 1767 / 654

Going ahead to step 4:
654 can be fit into 1767 2 times, resulting in a remainder of 459.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 1308 from 1767 leaves us with 459.
Take the next digit (0) from the dividend and append it to 459, then repeat: 4590 / 654

Going ahead to step 5:
654 goes into 4590 7 times with a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 127.0
Subtracting 4578 from 4590 leaves us with 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 654

Let's proceed to step 6:
When dividing 121 by 654, we get 0 with a remainder of 121.
Use 0 as the next digit of our solution. 
Result so far: 1270.0
Subtracting 0 from 121 leaves us with 121.
Bring next digit (2) of the dividend behind the 121 and repeat the process: 1212 / 654

On to step 7:
654 can be fit into 1212 1 times, resulting in a remainder of 558.
Put 1 as the next digit of the answer. 
Result so far: 12701.0
If we take 654 away from 1212, we end up with 558.
Grab the next digit (3) from the dividend, add it to 558, then carry on: 5583 / 654

On to step 8:
654 can be fit into 5583 8 times, resulting in a remainder of 351.
Record the quotient 8 as the next digit in the result. 
Result so far: 127018.0
Subtract 5232 from 5583 to get 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Let's proceed to step 9:
3510 divided by 654 is 5 with a remainder of 240.
Record the quotient 5 as the next digit in the result. 
Result so far: 127018.5
Subtracting 3270 from 3510 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 10:
When dividing 2400 by 654, we get 3 with a remainder of 438.
Use 3 as the next digit of our solution. 
Result so far: 127018.53
If we take 1962 away from 2400, we end up with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

On to step 11:
If we divide 4380 by 654, we get 6 and a remainder of 456.
The next digit of our result is 6. 
Result so far: 127018.536
Subtracting 3924 from 4380 leaves us with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Going ahead to step 12:
654 goes into 4560 6 times with a remainder of 636.
The number 6 becomes the next digit in our result. 
Result so far: 127018.5366
If we subtract 3924 from 4560, we get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

The final outcome is 127018.5366, with a leftover of 0.00636.
