We're dividing 35771603 by 681 
The aim is to understand the frequency of 681 in 35771603.

On to step 1:
When dividing 3 by 681, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 681

Moving on to step 2:
When dividing 35 by 681, we get 0 with a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Grab the next digit (7) from the dividend, add it to 35, then carry on: 357 / 681

On to step 3:
If we divide 357 by 681, we get 0 and a remainder of 357.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 357 after subtracting 0 from 357.
Grab the next digit (7) from the dividend, add it to 357, then carry on: 3577 / 681

Let's proceed to step 4:
If we divide 3577 by 681, we get 5 and a remainder of 172.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 3405 from 3577, we get 172.
Bring next digit (1) of the dividend behind the 172 and repeat the process: 1721 / 681

Step 5:
681 goes into 1721 2 times with a remainder of 359.
Use 2 as the next digit of our solution. 
Result so far: 52.0
Deduct 1362 from 1721 and we're left with 359.
Take the next digit (6) from the dividend and append it to 359, then repeat: 3596 / 681

Moving on to step 6:
When dividing 3596 by 681, we get 5 with a remainder of 191.
Use 5 as the next digit of our solution. 
Result so far: 525.0
Subtracting 3405 from 3596 leaves us with 191.
Grab the next digit (0) from the dividend, add it to 191, then carry on: 1910 / 681

Going ahead to step 7:
681 goes into 1910 2 times with a remainder of 548.
Write down 2 as next digit of the result. 
Result so far: 5252.0
Subtract 1362 from 1910 to get 548.
Fetch the next digit (3) from the dividend, attach it to 548 and continue: 5483 / 681

Let's proceed to step 8:
5483 divided by 681 is 8 with a remainder of 35.
Put 8 as the next digit of the answer. 
Result so far: 52528.0
Deduct 5448 from 5483 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 9:
681 can be fit into 350 0 times, resulting in a remainder of 350.
Record the quotient 0 as the next digit in the result. 
Result so far: 52528.0
Subtracting 0 from 350 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 10:
681 can be fit into 3500 5 times, resulting in a remainder of 95.
Put 5 as the next digit of the answer. 
Result so far: 52528.05
If we take 3405 away from 3500, we end up with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 11:
681 can be fit into 950 1 times, resulting in a remainder of 269.
Write down 1 as next digit of the result. 
Result so far: 52528.051
If we subtract 681 from 950, we get 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Advancing to step 12:
681 goes into 2690 3 times with a remainder of 647.
Put 3 as the next digit of the answer. 
Result so far: 52528.0513
Subtract 2043 from 2690 to get 647.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6470, and continue the process.

Step 13:
6470 divided by 681 is 9 with a remainder of 341.
Use 9 as the next digit of our solution. 
Result so far: 52528.05139
If we subtract 6129 from 6470, we get 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Advancing to step 14:
681 can be fit into 3410 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 52528.051395
If we subtract 3405 from 3410, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 15:
If we divide 50 by 681, we get 0 and a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 52528.051395
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 16:
The number 681 fits into 500 0 times, leaving a remainder of 500.
Put 0 as the next digit of the answer. 
Result so far: 52528.051395
Subtracting 0 from 500 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The final outcome is 52528.051395, with a leftover of 5e-07.
