53619673 divided by 681 
The aim is to understand the frequency of 681 in 53619673.

Step 1:
If we divide 5 by 681, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 681

Advancing to step 2:
The number 681 fits into 53 0 times, leaving a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Fetch the next digit (6) from the dividend, attach it to 53 and continue: 536 / 681

Going ahead to step 3:
536 divided by 681 is 0 with a remainder of 536.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 536 after subtracting 0 from 536.
Grab the next digit (1) from the dividend, add it to 536, then carry on: 5361 / 681

Let's proceed to step 4:
681 goes into 5361 7 times with a remainder of 594.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 4767 from 5361 and we're left with 594.
Fetch the next digit (9) from the dividend, attach it to 594 and continue: 5949 / 681

Step 5:
681 goes into 5949 8 times with a remainder of 501.
Put 8 as the next digit of the answer. 
Result so far: 78.0
Deduct 5448 from 5949 and we're left with 501.
Grab the next digit (6) from the dividend, add it to 501, then carry on: 5016 / 681

Step 6:
681 goes into 5016 7 times with a remainder of 249.
Use 7 as the next digit of our solution. 
Result so far: 787.0
If we subtract 4767 from 5016, we get 249.
Fetch the next digit (7) from the dividend, attach it to 249 and continue: 2497 / 681

Let's proceed to step 7:
681 goes into 2497 3 times with a remainder of 454.
Write down 3 as next digit of the result. 
Result so far: 7873.0
If we subtract 2043 from 2497, we get 454.
Append the next digit (3) from the dividend to 454 and continue with: 4543 / 681

Let's proceed to step 8:
If we divide 4543 by 681, we get 6 and a remainder of 457.
Use 6 as the next digit of our solution. 
Result so far: 78736.0
Deduct 4086 from 4543 and we're left with 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Moving on to step 9:
681 goes into 4570 6 times with a remainder of 484.
Record the quotient 6 as the next digit in the result. 
Result so far: 78736.6
If we take 4086 away from 4570, we end up with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

On to step 10:
4840 divided by 681 is 7 with a remainder of 73.
Use 7 as the next digit of our solution. 
Result so far: 78736.67
Subtracting 4767 from 4840 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 11:
When dividing 730 by 681, we get 1 with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 78736.671
Deduct 681 from 730 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 12:
681 goes into 490 0 times with a remainder of 490.
Record the quotient 0 as the next digit in the result. 
Result so far: 78736.671
Subtracting 0 from 490 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Going ahead to step 13:
When dividing 4900 by 681, we get 7 with a remainder of 133.
Write down 7 as next digit of the result. 
Result so far: 78736.67107
If we take 4767 away from 4900, we end up with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Step 14:
If we divide 1330 by 681, we get 1 and a remainder of 649.
The next digit of our result is 1. 
Result so far: 78736.671071
Deduct 681 from 1330 and we're left with 649.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6490, and continue the process.

Advancing to step 15:
681 can be fit into 6490 9 times, resulting in a remainder of 361.
The number 9 becomes the next digit in our result. 
Result so far: 78736.6710719
Subtract 6129 from 6490 to get 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Moving on to step 16:
When dividing 3610 by 681, we get 5 with a remainder of 205.
Use 5 as the next digit of our solution. 
Result so far: 78736.67107195
The remainder is 205 after subtracting 3405 from 3610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

The final outcome is 78736.67107195, with a leftover of 2.05e-07.
