55738138 ÷ 699 
The aim is to understand the frequency of 699 in 55738138.

Step 1:
699 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 699

Moving on to step 2:
The number 699 fits into 55 0 times, leaving a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Take the next digit (7) from the dividend and append it to 55, then repeat: 557 / 699

Moving on to step 3:
The number 699 fits into 557 0 times, leaving a remainder of 557.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 557 to get 557.
Fetch the next digit (3) from the dividend, attach it to 557 and continue: 5573 / 699

Step 4:
If we divide 5573 by 699, we get 7 and a remainder of 680.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 680 after subtracting 4893 from 5573.
Grab the next digit (8) from the dividend, add it to 680, then carry on: 6808 / 699

On to step 5:
699 can be fit into 6808 9 times, resulting in a remainder of 517.
Use 9 as the next digit of our solution. 
Result so far: 79.0
Subtracting 6291 from 6808 leaves us with 517.
Include the next digit (1) from the dividend after 517, then repeat: 5171 / 699

Step 6:
699 can be fit into 5171 7 times, resulting in a remainder of 278.
Use 7 as the next digit of our solution. 
Result so far: 797.0
If we take 4893 away from 5171, we end up with 278.
Grab the next digit (3) from the dividend, add it to 278, then carry on: 2783 / 699

Step 7:
The number 699 fits into 2783 3 times, leaving a remainder of 686.
Write down 3 as next digit of the result. 
Result so far: 7973.0
Deduct 2097 from 2783 and we're left with 686.
Grab the next digit (8) from the dividend, add it to 686, then carry on: 6868 / 699

Going ahead to step 8:
699 goes into 6868 9 times with a remainder of 577.
The next digit of our result is 9. 
Result so far: 79739.0
If we subtract 6291 from 6868, we get 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

On to step 9:
5770 divided by 699 is 8 with a remainder of 178.
Put 8 as the next digit of the answer. 
Result so far: 79739.8
If we take 5592 away from 5770, we end up with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

On to step 10:
1780 divided by 699 is 2 with a remainder of 382.
Write down 2 as next digit of the result. 
Result so far: 79739.82
Subtracting 1398 from 1780 leaves us with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Going ahead to step 11:
The number 699 fits into 3820 5 times, leaving a remainder of 325.
Put 5 as the next digit of the answer. 
Result so far: 79739.825
If we subtract 3495 from 3820, we get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Advancing to step 12:
When dividing 3250 by 699, we get 4 with a remainder of 454.
Use 4 as the next digit of our solution. 
Result so far: 79739.8254
Subtract 2796 from 3250 to get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Let's proceed to step 13:
699 goes into 4540 6 times with a remainder of 346.
Record the quotient 6 as the next digit in the result. 
Result so far: 79739.82546
Subtracting 4194 from 4540 leaves us with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Step 14:
699 can be fit into 3460 4 times, resulting in a remainder of 664.
The number 4 becomes the next digit in our result. 
Result so far: 79739.825464
Subtract 2796 from 3460 to get 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Let's proceed to step 15:
699 goes into 6640 9 times with a remainder of 349.
Use 9 as the next digit of our solution. 
Result so far: 79739.8254649
Subtract 6291 from 6640 to get 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Moving on to step 16:
If we divide 3490 by 699, we get 4 and a remainder of 694.
Use 4 as the next digit of our solution. 
Result so far: 79739.82546494
Subtracting 2796 from 3490 leaves us 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.

The final outcome is 79739.82546494, with a leftover of 6.94e-07.
