Let's divide 86778437 by 607
We want to divide 86778437 by 607.

Moving on to step 1:
The number 607 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 607

Step 2:
If we divide 86 by 607, we get 0 and a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Append the next digit (7) from the dividend to 86 and continue with: 867 / 607

Step 3:
If we divide 867 by 607, we get 1 and a remainder of 260.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 607 from 867 and we're left with 260.
Include the next digit (7) from the dividend after 260, then repeat: 2607 / 607

On to step 4:
607 can be fit into 2607 4 times, resulting in a remainder of 179.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtract 2428 from 2607 to get 179.
Append the next digit (8) from the dividend to 179 and continue with: 1798 / 607

Let's proceed to step 5:
When dividing 1798 by 607, we get 2 with a remainder of 584.
Use 2 as the next digit of our solution. 
Result so far: 142.0
Subtract 1214 from 1798 to get 584.
Append the next digit (4) from the dividend to 584 and continue with: 5844 / 607

Step 6:
If we divide 5844 by 607, we get 9 and a remainder of 381.
Record the quotient 9 as the next digit in the result. 
Result so far: 1429.0
The remainder is 381 after subtracting 5463 from 5844.
Append the next digit (3) from the dividend to 381 and continue with: 3813 / 607

On to step 7:
When dividing 3813 by 607, we get 6 with a remainder of 171.
Record the quotient 6 as the next digit in the result. 
Result so far: 14296.0
The remainder is 171 after subtracting 3642 from 3813.
Grab the next digit (7) from the dividend, add it to 171, then carry on: 1717 / 607

Advancing to step 8:
When dividing 1717 by 607, we get 2 with a remainder of 503.
Record the quotient 2 as the next digit in the result. 
Result so far: 142962.0
Subtract 1214 from 1717 to get 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Moving on to step 9:
607 can be fit into 5030 8 times, resulting in a remainder of 174.
Put 8 as the next digit of the answer. 
Result so far: 142962.8
Subtracting 4856 from 5030 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Moving on to step 10:
607 can be fit into 1740 2 times, resulting in a remainder of 526.
Record the quotient 2 as the next digit in the result. 
Result so far: 142962.82
Subtracting 1214 from 1740 leaves us with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Let's proceed to step 11:
If we divide 5260 by 607, we get 8 and a remainder of 404.
The number 8 becomes the next digit in our result. 
Result so far: 142962.828
Deduct 4856 from 5260 and we're left with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Advancing to step 12:
607 goes into 4040 6 times with a remainder of 398.
Record the quotient 6 as the next digit in the result. 
Result so far: 142962.8286
If we subtract 3642 from 4040, we get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Step 13:
If we divide 3980 by 607, we get 6 and a remainder of 338.
Write down 6 as next digit of the result. 
Result so far: 142962.82866
Subtracting 3642 from 3980 leaves us with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

After the division, we end up with 142962.82866 and a remainder of 0.000338.
