62001091 ÷ 641 
The aim is to understand the frequency of 641 in 62001091.

Advancing to step 1:
The number 641 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 641

Advancing to step 2:
641 can be fit into 62 0 times, resulting in a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 62, we end up with 62.
Grab the next digit (0) from the dividend, add it to 62, then carry on: 620 / 641

Advancing to step 3:
641 can be fit into 620 0 times, resulting in a remainder of 620.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 620 to get 620.
Bring next digit (0) of the dividend behind the 620 and repeat the process: 6200 / 641

Advancing to step 4:
641 can be fit into 6200 9 times, resulting in a remainder of 431.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 5769 away from 6200, we end up with 431.
Take the next digit (1) from the dividend and append it to 431, then repeat: 4311 / 641

Step 5:
4311 divided by 641 is 6 with a remainder of 465.
Write down 6 as next digit of the result. 
Result so far: 96.0
Subtract 3846 from 4311 to get 465.
Include the next digit (0) from the dividend after 465, then repeat: 4650 / 641

Going ahead to step 6:
When dividing 4650 by 641, we get 7 with a remainder of 163.
The next digit of our result is 7. 
Result so far: 967.0
Subtract 4487 from 4650 to get 163.
Fetch the next digit (9) from the dividend, attach it to 163 and continue: 1639 / 641

Advancing to step 7:
If we divide 1639 by 641, we get 2 and a remainder of 357.
The next digit of our result is 2. 
Result so far: 9672.0
Subtracting 1282 from 1639 leaves us with 357.
Take the next digit (1) from the dividend and append it to 357, then repeat: 3571 / 641

Advancing to step 8:
641 goes into 3571 5 times with a remainder of 366.
Write down 5 as next digit of the result. 
Result so far: 96725.0
Deduct 3205 from 3571 and we're left with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

On to step 9:
If we divide 3660 by 641, we get 5 and a remainder of 455.
The next digit of our result is 5. 
Result so far: 96725.5
Subtract 3205 from 3660 to get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

On to step 10:
4550 divided by 641 is 7 with a remainder of 63.
Record the quotient 7 as the next digit in the result. 
Result so far: 96725.57
If we take 4487 away from 4550, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 11:
641 can be fit into 630 0 times, resulting in a remainder of 630.
Record the quotient 0 as the next digit in the result. 
Result so far: 96725.57
If we take 0 away from 630, we end up with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Moving on to step 12:
6300 divided by 641 is 9 with a remainder of 531.
The number 9 becomes the next digit in our result. 
Result so far: 96725.5709
Subtract 5769 from 6300 to get 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

On to step 13:
If we divide 5310 by 641, we get 8 and a remainder of 182.
Record the quotient 8 as the next digit in the result. 
Result so far: 96725.57098
If we subtract 5128 from 5310, we get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Advancing to step 14:
641 can be fit into 1820 2 times, resulting in a remainder of 538.
Use 2 as the next digit of our solution. 
Result so far: 96725.570982
If we take 1282 away from 1820, we end up with 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 15:
The number 641 fits into 5380 8 times, leaving a remainder of 252.
The number 8 becomes the next digit in our result. 
Result so far: 96725.5709828
If we take 5128 away from 5380, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 16:
The number 641 fits into 2520 3 times, leaving a remainder of 597.
The number 3 becomes the next digit in our result. 
Result so far: 96725.57098283
Subtract 1923 from 2520 to get 597.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5970, and continue the process.

After the division, we end up with 96725.57098283 and a remainder of 5.97e-07.
