Step 1:
The number 607 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 607

Advancing to step 2:
When dividing 86 by 607, we get 0 with 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.
Take the next digit (6) from the dividend and append it to 86, then repeat: 866 / 607

Advancing to step 3:
866 divided by 607 is 1 with a remainder of 259.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 607 from 866 to get 259.

Advancing to step 4:
When dividing 2591 by 607, we get 4 with a remainder of 163.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 2428 from 2591 and we're left with 163.
Take the next digit (2) from the dividend and append it to 163, then repeat: 1632 / 607

Step 5:
The number 607 fits into 1632 2 times, leaving a remainder of 418.
The number 2 becomes the next digit in our result. 
Result so far: 142.0
If we take 1214 away from 1632, we end up with 418.
Include the next digit (9) from the dividend after 418, then repeat: 4189 / 607

Moving on to step 6:
When dividing 4189 by 607, we get 6 with a remainder of 547.
The number 6 becomes the next digit in our result. 
Result so far: 1426.0
Subtracting 3642 from 4189 leaves us with 547.
Take the next digit (7) from the dividend and append it to 547, then repeat: 5477 / 607

On to step 7:
5477 divided by 607 is 9 with a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 14269.0
Subtract 5463 from 5477 to get 14.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 607

Moving on to step 8:
When dividing 149 by 607, we get 0 with a remainder of 149.
The next digit of our result is 0. 
Result so far: 142690.0
Deduct 0 from 149 and we're left with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

On to step 9:
1490 divided by 607 is 2 with a remainder of 276.
The next digit of our result is 2. 
Result so far: 142690.2
Subtracting 1214 from 1490 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Moving on to step 10:
If we divide 2760 by 607, we get 4 and a remainder of 332.
Write down 4 as next digit of the result. 
Result so far: 142690.24
Subtract 2428 from 2760 to get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Going ahead to step 11:
607 can be fit into 3320 5 times, resulting in a remainder of 285.
Record the quotient 5 as the next digit in the result. 
Result so far: 142690.245
If we take 3035 away from 3320, we end up with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Advancing to step 12:
607 goes into 2850 4 times with a remainder of 422.
Write down 4 as next digit of the result. 
Result so far: 142690.2454
Subtracting 2428 from 2850 leaves us with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

On to step 13:
When dividing 4220 by 607, we get 6 with a remainder of 578.
Write down 6 as next digit of the result. 
Result so far: 142690.24546
If we subtract 3642 from 4220, we get 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Let's proceed to step 14:
The number 607 fits into 5780 9 times, leaving a remainder of 317.
Write down 9 as next digit of the result. 
Result so far: 142690.245469
The remainder is 317 after subtracting 5463 from 5780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Let's proceed to step 15:
3170 divided by 607 is 5 with a remainder of 135.
The number 5 becomes the next digit in our result. 
Result so far: 142690.2454695
The remainder is 135 after subtracting 3035 from 3170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 16:
The number 607 fits into 1350 2 times, leaving a remainder of 136.
The next digit of our result is 2. 
Result so far: 142690.24546952
Subtracting 1214 from 1350 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

In conclusion, the division gives 142690.24546952 with a balance of 1.36e-07.
