We're dividing 91739797 by 659 
The aim is to understand the frequency of 659 in 91739797.

Going ahead to step 1:
When dividing 9 by 659, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 659

On to step 2:
The number 659 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 take 0 away from 91, we end up with 91.
Include the next digit (7) from the dividend after 91, then repeat: 917 / 659

Going ahead to step 3:
659 goes into 917 1 times with a remainder of 258.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 258 after subtracting 659 from 917.
Append the next digit (3) from the dividend to 258 and continue with: 2583 / 659

Let's proceed to step 4:
2583 divided by 659 is 3 with a remainder of 606.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 1977 from 2583, we get 606.
Fetch the next digit (9) from the dividend, attach it to 606 and continue: 6069 / 659

Step 5:
When dividing 6069 by 659, we get 9 with a remainder of 138.
Record the quotient 9 as the next digit in the result. 
Result so far: 139.0
The remainder is 138 after subtracting 5931 from 6069.
Bring next digit (7) of the dividend behind the 138 and repeat the process: 1387 / 659

Let's proceed to step 6:
The number 659 fits into 1387 2 times, leaving a remainder of 69.
Write down 2 as next digit of the result. 
Result so far: 1392.0
Subtracting 1318 from 1387 leaves us with 69.
Append the next digit (9) from the dividend to 69 and continue with: 699 / 659

Step 7:
659 goes into 699 1 times with a remainder of 40.
Put 1 as the next digit of the answer. 
Result so far: 13921.0
Deduct 659 from 699 and we're left with 40.
Fetch the next digit (7) from the dividend, attach it to 40 and continue: 407 / 659

Step 8:
659 can be fit into 407 0 times, resulting in a remainder of 407.
The next digit of our result is 0. 
Result so far: 139210.0
The remainder is 407 after subtracting 0 from 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Step 9:
The number 659 fits into 4070 6 times, leaving a remainder of 116.
The next digit of our result is 6. 
Result so far: 139210.6
If we take 3954 away from 4070, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 10:
659 goes into 1160 1 times with a remainder of 501.
Write down 1 as next digit of the result. 
Result so far: 139210.61
If we take 659 away from 1160, we end up with 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Advancing to step 11:
659 can be fit into 5010 7 times, resulting in a remainder of 397.
Record the quotient 7 as the next digit in the result. 
Result so far: 139210.617
Deduct 4613 from 5010 and we're left with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Step 12:
3970 divided by 659 is 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 139210.6176
If we subtract 3954 from 3970, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
When dividing 160 by 659, we get 0 with a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 139210.6176
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 14:
When dividing 1600 by 659, we get 2 with a remainder of 282.
Record the quotient 2 as the next digit in the result. 
Result so far: 139210.617602
Deduct 1318 from 1600 and we're left 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.

On to step 15:
2820 divided by 659 is 4 with a remainder of 184.
Put 4 as the next digit of the answer. 
Result so far: 139210.6176024
Subtracting 2636 from 2820 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 16:
659 goes into 1840 2 times with a remainder of 522.
The number 2 becomes the next digit in our result. 
Result so far: 139210.61760242
The remainder is 522 after subtracting 1318 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

The final outcome is 139210.61760242, with a leftover of 5.22e-07.
