We divide 69541042 by 781
The aim is to understand the frequency of 781 in 69541042.

Going ahead to step 1:
If we divide 6 by 781, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 781

On to step 2:
781 goes into 69 0 times with a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 69 to get 69.
Fetch the next digit (5) from the dividend, attach it to 69 and continue: 695 / 781

Step 3:
781 goes into 695 0 times with a remainder of 695.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 695 and we're left with 695.
Fetch the next digit (4) from the dividend, attach it to 695 and continue: 6954 / 781

Let's proceed to step 4:
6954 divided by 781 is 8 with a remainder of 706.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 6248 from 6954 and we're left with 706.
Append the next digit (1) from the dividend to 706 and continue with: 7061 / 781

On to step 5:
The number 781 fits into 7061 9 times, leaving a remainder of 32.
The next digit of our result is 9. 
Result so far: 89.0
Subtract 7029 from 7061 to get 32.
Include the next digit (0) from the dividend after 32, then repeat: 320 / 781

Moving on to step 6:
When dividing 320 by 781, we get 0 with a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 890.0
If we subtract 0 from 320, we get 320.
Append the next digit (4) from the dividend to 320 and continue with: 3204 / 781

Step 7:
3204 divided by 781 is 4 with a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 8904.0
Deduct 3124 from 3204 and we're left with 80.
Include the next digit (2) from the dividend after 80, then repeat: 802 / 781

Moving on to step 8:
781 goes into 802 1 times with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 89041.0
Subtract 781 from 802 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 9:
The number 781 fits into 210 0 times, leaving a remainder of 210.
Use 0 as the next digit of our solution. 
Result so far: 89041.0
Deduct 0 from 210 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 10:
If we divide 2100 by 781, we get 2 and a remainder of 538.
Record the quotient 2 as the next digit in the result. 
Result so far: 89041.02
Subtract 1562 from 2100 to get 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Step 11:
781 can be fit into 5380 6 times, resulting in a remainder of 694.
Record the quotient 6 as the next digit in the result. 
Result so far: 89041.026
Deduct 4686 from 5380 and we're left with 694.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6940, and continue the process.

Let's proceed to step 12:
781 can be fit into 6940 8 times, resulting in a remainder of 692.
Write down 8 as next digit of the result. 
Result so far: 89041.0268
Deduct 6248 from 6940 and we're left with 692.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

On to step 13:
6920 divided by 781 is 8 with a remainder of 672.
Record the quotient 8 as the next digit in the result. 
Result so far: 89041.02688
If we take 6248 away from 6920, we end up with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

The final result is 89041.02688 with a remainder of 0.000672.
