We're dividing 63998342 by 860 
The aim is to understand the frequency of 860 in 63998342.

Going ahead to step 1:
860 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 860

On to step 2:
63 divided by 860 is 0 with a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Append the next digit (9) from the dividend to 63 and continue with: 639 / 860

On to step 3:
If we divide 639 by 860, we get 0 and a remainder of 639.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 639, we get 639.
Bring next digit (9) of the dividend behind the 639 and repeat the process: 6399 / 860

Going ahead to step 4:
The number 860 fits into 6399 7 times, leaving a remainder of 379.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 379 after subtracting 6020 from 6399.
Take the next digit (8) from the dividend and append it to 379, then repeat: 3798 / 860

Moving on to step 5:
If we divide 3798 by 860, we get 4 and a remainder of 358.
Write down 4 as next digit of the result. 
Result so far: 74.0
If we subtract 3440 from 3798, we get 358.
Take the next digit (3) from the dividend and append it to 358, then repeat: 3583 / 860

Moving on to step 6:
The number 860 fits into 3583 4 times, leaving a remainder of 143.
Put 4 as the next digit of the answer. 
Result so far: 744.0
The remainder is 143 after subtracting 3440 from 3583.
Fetch the next digit (4) from the dividend, attach it to 143 and continue: 1434 / 860

On to step 7:
When dividing 1434 by 860, we get 1 with a remainder of 574.
Write down 1 as next digit of the result. 
Result so far: 7441.0
Subtract 860 from 1434 to get 574.
Append the next digit (2) from the dividend to 574 and continue with: 5742 / 860

On to step 8:
860 goes into 5742 6 times with a remainder of 582.
Use 6 as the next digit of our solution. 
Result so far: 74416.0
If we subtract 5160 from 5742, we get 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

Going ahead to step 9:
When dividing 5820 by 860, we get 6 with a remainder of 660.
Record the quotient 6 as the next digit in the result. 
Result so far: 74416.6
Deduct 5160 from 5820 and we're left with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Let's proceed to step 10:
The number 860 fits into 6600 7 times, leaving a remainder of 580.
The next digit of our result is 7. 
Result so far: 74416.67
If we take 6020 away from 6600, we end up with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Going ahead to step 11:
860 goes into 5800 6 times with a remainder of 640.
Record the quotient 6 as the next digit in the result. 
Result so far: 74416.676
Deduct 5160 from 5800 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 12:
6400 divided by 860 is 7 with a remainder of 380.
The next digit of our result is 7. 
Result so far: 74416.6767
Deduct 6020 from 6400 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 13:
3800 divided by 860 is 4 with a remainder of 360.
Record the quotient 4 as the next digit in the result. 
Result so far: 74416.67674
The remainder is 360 after subtracting 3440 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 14:
The number 860 fits into 3600 4 times, leaving a remainder of 160.
Write down 4 as next digit of the result. 
Result so far: 74416.676744
The remainder is 160 after subtracting 3440 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Our division results in 74416.676744 with a remaining 1.6e-05.
