81706139 ÷ 658 
The aim is to understand the frequency of 658 in 81706139.

Let's proceed to step 1:
658 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 658

On to step 2:
The number 658 fits into 81 0 times, leaving a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Take the next digit (7) from the dividend and append it to 81, then repeat: 817 / 658

Step 3:
658 goes into 817 1 times with a remainder of 159.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 658 from 817 to get 159.
Fetch the next digit (0) from the dividend, attach it to 159 and continue: 1590 / 658

On to step 4:
The number 658 fits into 1590 2 times, leaving a remainder of 274.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 1316 away from 1590, we end up with 274.
Include the next digit (6) from the dividend after 274, then repeat: 2746 / 658

Step 5:
If we divide 2746 by 658, we get 4 and a remainder of 114.
Use 4 as the next digit of our solution. 
Result so far: 124.0
Deduct 2632 from 2746 and we're left with 114.
Grab the next digit (1) from the dividend, add it to 114, then carry on: 1141 / 658

Step 6:
If we divide 1141 by 658, we get 1 and a remainder of 483.
Use 1 as the next digit of our solution. 
Result so far: 1241.0
Deduct 658 from 1141 and we're left with 483.
Include the next digit (3) from the dividend after 483, then repeat: 4833 / 658

Going ahead to step 7:
The number 658 fits into 4833 7 times, leaving a remainder of 227.
Write down 7 as next digit of the result. 
Result so far: 12417.0
If we take 4606 away from 4833, we end up with 227.
Take the next digit (9) from the dividend and append it to 227, then repeat: 2279 / 658

Let's proceed to step 8:
If we divide 2279 by 658, we get 3 and a remainder of 305.
Write down 3 as next digit of the result. 
Result so far: 124173.0
Deduct 1974 from 2279 and we're left with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Moving on to step 9:
If we divide 3050 by 658, we get 4 and a remainder of 418.
Write down 4 as next digit of the result. 
Result so far: 124173.4
If we subtract 2632 from 3050, we get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Moving on to step 10:
The number 658 fits into 4180 6 times, leaving a remainder of 232.
Write down 6 as next digit of the result. 
Result so far: 124173.46
If we subtract 3948 from 4180, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Advancing to step 11:
658 can be fit into 2320 3 times, resulting in a remainder of 346.
Use 3 as the next digit of our solution. 
Result so far: 124173.463
The remainder is 346 after subtracting 1974 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Let's proceed to step 12:
658 can be fit into 3460 5 times, resulting in a remainder of 170.
Put 5 as the next digit of the answer. 
Result so far: 124173.4635
Deduct 3290 from 3460 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 13:
If we divide 1700 by 658, we get 2 and a remainder of 384.
Write down 2 as next digit of the result. 
Result so far: 124173.46352
The remainder is 384 after subtracting 1316 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Moving on to step 14:
When dividing 3840 by 658, we get 5 with a remainder of 550.
Use 5 as the next digit of our solution. 
Result so far: 124173.463525
If we subtract 3290 from 3840, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Advancing to step 15:
The number 658 fits into 5500 8 times, leaving a remainder of 236.
Record the quotient 8 as the next digit in the result. 
Result so far: 124173.4635258
Deduct 5264 from 5500 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Advancing to step 16:
The number 658 fits into 2360 3 times, leaving a remainder of 386.
Record the quotient 3 as the next digit in the result. 
Result so far: 124173.46352583
If we take 1974 away from 2360, we end up with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Our division results in 124173.46352583 with a remaining 3.86e-07.
