We divide 91932561 by 687
The aim is to understand the frequency of 687 in 91932561.

Advancing to step 1:
When dividing 9 by 687, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 687

Step 2:
The number 687 fits into 91 0 times, leaving a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Take the next digit (9) from the dividend and append it to 91, then repeat: 919 / 687

Let's proceed to step 3:
When dividing 919 by 687, we get 1 with a remainder of 232.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 687 away from 919, we end up with 232.
Grab the next digit (3) from the dividend, add it to 232, then carry on: 2323 / 687

On to step 4:
687 goes into 2323 3 times with a remainder of 262.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 2061 from 2323 leaves us with 262.
Take the next digit (2) from the dividend and append it to 262, then repeat: 2622 / 687

Advancing to step 5:
The number 687 fits into 2622 3 times, leaving a remainder of 561.
Record the quotient 3 as the next digit in the result. 
Result so far: 133.0
Subtracting 2061 from 2622 leaves us with 561.
Grab the next digit (5) from the dividend, add it to 561, then carry on: 5615 / 687

Step 6:
687 can be fit into 5615 8 times, resulting in a remainder of 119.
Record the quotient 8 as the next digit in the result. 
Result so far: 1338.0
Subtracting 5496 from 5615 leaves us with 119.
Append the next digit (6) from the dividend to 119 and continue with: 1196 / 687

Step 7:
687 can be fit into 1196 1 times, resulting in a remainder of 509.
The next digit of our result is 1. 
Result so far: 13381.0
If we subtract 687 from 1196, we get 509.
Bring next digit (1) of the dividend behind the 509 and repeat the process: 5091 / 687

Step 8:
If we divide 5091 by 687, we get 7 and a remainder of 282.
The number 7 becomes the next digit in our result. 
Result so far: 133817.0
If we take 4809 away from 5091, we end up with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Moving on to step 9:
687 can be fit into 2820 4 times, resulting in a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 133817.4
Subtracting 2748 from 2820 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 10:
When dividing 720 by 687, we get 1 with a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 133817.41
Subtract 687 from 720 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 11:
When dividing 330 by 687, we get 0 with a remainder of 330.
Put 0 as the next digit of the answer. 
Result so far: 133817.41
Deduct 0 from 330 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 12:
687 can be fit into 3300 4 times, resulting in a remainder of 552.
Write down 4 as next digit of the result. 
Result so far: 133817.4104
Subtracting 2748 from 3300 leaves us with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

On to step 13:
If we divide 5520 by 687, we get 8 and a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 133817.41048
If we subtract 5496 from 5520, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
687 goes into 240 0 times with a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 133817.41048
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 15:
If we divide 2400 by 687, we get 3 and a remainder of 339.
The number 3 becomes the next digit in our result. 
Result so far: 133817.4104803
Deduct 2061 from 2400 and we're left with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Moving on to step 16:
687 goes into 3390 4 times with a remainder of 642.
Record the quotient 4 as the next digit in the result. 
Result so far: 133817.41048034
Subtract 2748 from 3390 to get 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

The quotient of the division is 133817.41048034, and the remainder is 6.42e-07.
