Let's divide 19967188 by 786
The aim is to understand the frequency of 786 in 19967188.

Advancing to step 1:
When dividing 1 by 786, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 786

Advancing to step 2:
The number 786 fits into 19 0 times, leaving a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 786

Going ahead to step 3:
199 divided by 786 is 0 with a remainder of 199.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 199 and we're left with 199.
Fetch the next digit (6) from the dividend, attach it to 199 and continue: 1996 / 786

Advancing to step 4:
If we divide 1996 by 786, we get 2 and a remainder of 424.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1572 from 1996 and we're left with 424.
Bring next digit (7) of the dividend behind the 424 and repeat the process: 4247 / 786

Let's proceed to step 5:
786 goes into 4247 5 times with a remainder of 317.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we subtract 3930 from 4247, we get 317.
Grab the next digit (1) from the dividend, add it to 317, then carry on: 3171 / 786

Advancing to step 6:
786 can be fit into 3171 4 times, resulting in a remainder of 27.
The next digit of our result is 4. 
Result so far: 254.0
The remainder is 27 after subtracting 3144 from 3171.
Take the next digit (8) from the dividend and append it to 27, then repeat: 278 / 786

Going ahead to step 7:
278 divided by 786 is 0 with a remainder of 278.
Write down 0 as next digit of the result. 
Result so far: 2540.0
Subtracting 0 from 278 leaves us with 278.
Take the next digit (8) from the dividend and append it to 278, then repeat: 2788 / 786

Advancing to step 8:
786 can be fit into 2788 3 times, resulting in a remainder of 430.
Record the quotient 3 as the next digit in the result. 
Result so far: 25403.0
The remainder is 430 after subtracting 2358 from 2788.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Step 9:
When dividing 4300 by 786, we get 5 with a remainder of 370.
The number 5 becomes the next digit in our result. 
Result so far: 25403.5
If we take 3930 away from 4300, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Step 10:
When dividing 3700 by 786, we get 4 with a remainder of 556.
Write down 4 as next digit of the result. 
Result so far: 25403.54
Subtracting 3144 from 3700 leaves us with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Step 11:
The number 786 fits into 5560 7 times, leaving a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 25403.547
The remainder is 58 after subtracting 5502 from 5560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 12:
When dividing 580 by 786, we get 0 with a remainder of 580.
Record the quotient 0 as the next digit in the result. 
Result so far: 25403.547
If we subtract 0 from 580, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Going ahead to step 13:
786 can be fit into 5800 7 times, resulting in a remainder of 298.
The number 7 becomes the next digit in our result. 
Result so far: 25403.54707
The remainder is 298 after subtracting 5502 from 5800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Going ahead to step 14:
2980 divided by 786 is 3 with a remainder of 622.
Record the quotient 3 as the next digit in the result. 
Result so far: 25403.547073
Deduct 2358 from 2980 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.

Going ahead to step 15:
The number 786 fits into 6220 7 times, leaving a remainder of 718.
Write down 7 as next digit of the result. 
Result so far: 25403.5470737
Deduct 5502 from 6220 and we're left with 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

Advancing to step 16:
786 goes into 7180 9 times with a remainder of 106.
The next digit of our result is 9. 
Result so far: 25403.54707379
Deduct 7074 from 7180 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

The quotient of the division is 25403.54707379, and the remainder is 1.06e-07.
