70191140 ÷ 807 
The aim is to understand the frequency of 807 in 70191140.

On to step 1:
807 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 807

Going ahead to step 2:
807 can be fit into 70 0 times, resulting in a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Take the next digit (1) from the dividend and append it to 70, then repeat: 701 / 807

Step 3:
807 can be fit into 701 0 times, resulting in a remainder of 701.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 701, we end up with 701.
Grab the next digit (9) from the dividend, add it to 701, then carry on: 7019 / 807

Let's proceed to step 4:
The number 807 fits into 7019 8 times, leaving a remainder of 563.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 6456 from 7019, we get 563.
Append the next digit (1) from the dividend to 563 and continue with: 5631 / 807

Let's proceed to step 5:
The number 807 fits into 5631 6 times, leaving a remainder of 789.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
Subtract 4842 from 5631 to get 789.
Fetch the next digit (1) from the dividend, attach it to 789 and continue: 7891 / 807

Let's proceed to step 6:
The number 807 fits into 7891 9 times, leaving a remainder of 628.
The number 9 becomes the next digit in our result. 
Result so far: 869.0
The remainder is 628 after subtracting 7263 from 7891.
Take the next digit (4) from the dividend and append it to 628, then repeat: 6284 / 807

Step 7:
6284 divided by 807 is 7 with a remainder of 635.
Record the quotient 7 as the next digit in the result. 
Result so far: 8697.0
If we subtract 5649 from 6284, we get 635.
Append the next digit (0) from the dividend to 635 and continue with: 6350 / 807

Going ahead to step 8:
6350 divided by 807 is 7 with a remainder of 701.
Use 7 as the next digit of our solution. 
Result so far: 86977.0
If we subtract 5649 from 6350, we get 701.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7010, and continue the process.

Going ahead to step 9:
The number 807 fits into 7010 8 times, leaving a remainder of 554.
The next digit of our result is 8. 
Result so far: 86977.8
Subtracting 6456 from 7010 leaves us with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

On to step 10:
807 goes into 5540 6 times with a remainder of 698.
The number 6 becomes the next digit in our result. 
Result so far: 86977.86
Subtracting 4842 from 5540 leaves us with 698.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

Step 11:
The number 807 fits into 6980 8 times, leaving a remainder of 524.
Put 8 as the next digit of the answer. 
Result so far: 86977.868
If we take 6456 away from 6980, we end up with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

On to step 12:
807 goes into 5240 6 times with a remainder of 398.
The number 6 becomes the next digit in our result. 
Result so far: 86977.8686
The remainder is 398 after subtracting 4842 from 5240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Moving on to step 13:
807 goes into 3980 4 times with a remainder of 752.
Record the quotient 4 as the next digit in the result. 
Result so far: 86977.86864
If we subtract 3228 from 3980, we get 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Step 14:
If we divide 7520 by 807, we get 9 and a remainder of 257.
The number 9 becomes the next digit in our result. 
Result so far: 86977.868649
If we subtract 7263 from 7520, we get 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Going ahead to step 15:
The number 807 fits into 2570 3 times, leaving a remainder of 149.
The number 3 becomes the next digit in our result. 
Result so far: 86977.8686493
Subtract 2421 from 2570 to get 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Moving on to step 16:
1490 divided by 807 is 1 with a remainder of 683.
Use 1 as the next digit of our solution. 
Result so far: 86977.86864931
If we take 807 away from 1490, we end up with 683.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6830, and continue the process.

Our division results in 86977.86864931 with a remaining 6.83e-07.
