Let's divide 990148 by 807
The aim is to understand the frequency of 807 in 990148.

Step 1:
When dividing 9 by 807, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 807

On to step 2:
If we divide 99 by 807, we get 0 and a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Take the next digit (0) from the dividend and append it to 99, then repeat: 990 / 807

Step 3:
807 goes into 990 1 times with a remainder of 183.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 807 from 990 leaves us with 183.
Take the next digit (1) from the dividend and append it to 183, then repeat: 1831 / 807

Let's proceed to step 4:
When dividing 1831 by 807, we get 2 with a remainder of 217.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 217 after subtracting 1614 from 1831.
Append the next digit (4) from the dividend to 217 and continue with: 2174 / 807

On to step 5:
2174 divided by 807 is 2 with a remainder of 560.
The next digit of our result is 2. 
Result so far: 122.0
If we take 1614 away from 2174, we end up with 560.
Grab the next digit (8) from the dividend, add it to 560, then carry on: 5608 / 807

Going ahead to step 6:
When dividing 5608 by 807, we get 6 with a remainder of 766.
Put 6 as the next digit of the answer. 
Result so far: 1226.0
If we subtract 4842 from 5608, we get 766.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7660, and continue the process.

Advancing to step 7:
When dividing 7660 by 807, we get 9 with a remainder of 397.
Put 9 as the next digit of the answer. 
Result so far: 1226.9
Subtract 7263 from 7660 to get 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Moving on to step 8:
The number 807 fits into 3970 4 times, leaving a remainder of 742.
Record the quotient 4 as the next digit in the result. 
Result so far: 1226.94
Deduct 3228 from 3970 and we're left with 742.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

Let's proceed to step 9:
If we divide 7420 by 807, we get 9 and a remainder of 157.
The next digit of our result is 9. 
Result so far: 1226.949
The remainder is 157 after subtracting 7263 from 7420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Going ahead to step 10:
If we divide 1570 by 807, we get 1 and a remainder of 763.
Record the quotient 1 as the next digit in the result. 
Result so far: 1226.9491
Deduct 807 from 1570 and we're left with 763.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7630, and continue the process.

Going ahead to step 11:
When dividing 7630 by 807, we get 9 with a remainder of 367.
Put 9 as the next digit of the answer. 
Result so far: 1226.94919
Subtracting 7263 from 7630 leaves us with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Going ahead to step 12:
807 can be fit into 3670 4 times, resulting in a remainder of 442.
Use 4 as the next digit of our solution. 
Result so far: 1226.949194
If we take 3228 away from 3670, we end up with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Step 13:
The number 807 fits into 4420 5 times, leaving a remainder of 385.
Write down 5 as next digit of the result. 
Result so far: 1226.9491945
If we take 4035 away from 4420, we end up with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Advancing to step 14:
807 can be fit into 3850 4 times, resulting in a remainder of 622.
The next digit of our result is 4. 
Result so far: 1226.94919454
Deduct 3228 from 3850 and we're left with 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

The quotient of the division is 1226.94919454, and the remainder is 6.22e-07.
