We divide 638488 by 86
Let's see how many times 86 fits into 638488.

Going ahead to step 1:
If we divide 6 by 86, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 86

Moving on to step 2:
86 goes into 63 0 times with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Grab the next digit (8) from the dividend, add it to 63, then carry on: 638 / 86

Let's proceed to step 3:
The number 86 fits into 638 7 times, leaving a remainder of 36.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 602 away from 638, we end up with 36.
Include the next digit (4) from the dividend after 36, then repeat: 364 / 86

Moving on to step 4:
The number 86 fits into 364 4 times, leaving a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 74.0
If we subtract 344 from 364, we get 20.
Include the next digit (8) from the dividend after 20, then repeat: 208 / 86

Advancing to step 5:
86 goes into 208 2 times with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 742.0
Subtracting 172 from 208 leaves us with 36.
Grab the next digit (8) from the dividend, add it to 36, then carry on: 368 / 86

Going ahead to step 6:
The number 86 fits into 368 4 times, leaving a remainder of 24.
The next digit of our result is 4. 
Result so far: 7424.0
Subtracting 344 from 368 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 7:
240 divided by 86 is 2 with a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 7424.2
Deduct 172 from 240 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 8:
The number 86 fits into 680 7 times, leaving a remainder of 78.
Record the quotient 7 as the next digit in the result. 
Result so far: 7424.27
If we take 602 away from 680, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 9:
780 divided by 86 is 9 with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 7424.279
Subtracting 774 from 780 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 10:
60 divided by 86 is 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 7424.279
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 11:
600 divided by 86 is 6 with a remainder of 84.
The next digit of our result is 6. 
Result so far: 7424.27906
If we subtract 516 from 600, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 12:
86 can be fit into 840 9 times, resulting in a remainder of 66.
Record the quotient 9 as the next digit in the result. 
Result so far: 7424.279069
If we subtract 774 from 840, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 13:
When dividing 660 by 86, we get 7 with a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 7424.2790697
Deduct 602 from 660 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 14:
86 can be fit into 580 6 times, resulting in a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 7424.27906976
Deduct 516 from 580 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 7424.27906976, with a leftover of 6.4e-08.
