16698417 divided by 781 
The aim is to understand the frequency of 781 in 16698417.

Going ahead to step 1:
When dividing 1 by 781, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 781

Step 2:
The number 781 fits into 16 0 times, leaving a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 781

On to step 3:
781 goes into 166 0 times with a remainder of 166.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 166 to get 166.
Grab the next digit (9) from the dividend, add it to 166, then carry on: 1669 / 781

Step 4:
If we divide 1669 by 781, we get 2 and a remainder of 107.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 1562 from 1669, we get 107.
Bring next digit (8) of the dividend behind the 107 and repeat the process: 1078 / 781

On to step 5:
781 goes into 1078 1 times with a remainder of 297.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtract 781 from 1078 to get 297.
Bring next digit (4) of the dividend behind the 297 and repeat the process: 2974 / 781

On to step 6:
The number 781 fits into 2974 3 times, leaving a remainder of 631.
Record the quotient 3 as the next digit in the result. 
Result so far: 213.0
Subtracting 2343 from 2974 leaves us with 631.
Grab the next digit (1) from the dividend, add it to 631, then carry on: 6311 / 781

On to step 7:
781 can be fit into 6311 8 times, resulting in a remainder of 63.
Use 8 as the next digit of our solution. 
Result so far: 2138.0
Subtract 6248 from 6311 to get 63.
Bring next digit (7) of the dividend behind the 63 and repeat the process: 637 / 781

Moving on to step 8:
781 can be fit into 637 0 times, resulting in a remainder of 637.
Put 0 as the next digit of the answer. 
Result so far: 21380.0
If we subtract 0 from 637, we get 637.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

Advancing to step 9:
The number 781 fits into 6370 8 times, leaving a remainder of 122.
Put 8 as the next digit of the answer. 
Result so far: 21380.8
If we take 6248 away from 6370, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 10:
781 can be fit into 1220 1 times, resulting in a remainder of 439.
Write down 1 as next digit of the result. 
Result so far: 21380.81
Subtracting 781 from 1220 leaves us with 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Moving on to step 11:
If we divide 4390 by 781, we get 5 and a remainder of 485.
Put 5 as the next digit of the answer. 
Result so far: 21380.815
If we take 3905 away from 4390, we end up with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Step 12:
If we divide 4850 by 781, we get 6 and a remainder of 164.
Use 6 as the next digit of our solution. 
Result so far: 21380.8156
The remainder is 164 after subtracting 4686 from 4850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 13:
When dividing 1640 by 781, we get 2 with a remainder of 78.
Write down 2 as next digit of the result. 
Result so far: 21380.81562
If we subtract 1562 from 1640, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 14:
The number 781 fits into 780 0 times, leaving a remainder of 780.
Write down 0 as next digit of the result. 
Result so far: 21380.81562
If we take 0 away from 780, we end up with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Advancing to step 15:
781 can be fit into 7800 9 times, resulting in a remainder of 771.
The number 9 becomes the next digit in our result. 
Result so far: 21380.8156209
If we subtract 7029 from 7800, we get 771.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7710, and continue the process.

Moving on to step 16:
781 can be fit into 7710 9 times, resulting in a remainder of 681.
The number 9 becomes the next digit in our result. 
Result so far: 21380.81562099
The remainder is 681 after subtracting 7029 from 7710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6810, and continue the process.

The final outcome is 21380.81562099, with a leftover of 6.81e-07.
