We look at the division of 137990 by 86 
Let's see how many times 86 fits into 137990.

Let's proceed to step 1:
1 divided by 86 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 86

Step 2:
86 goes into 13 0 times with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 86

Going ahead to step 3:
86 can be fit into 137 1 times, resulting in a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 86 from 137 leaves us with 51.
Bring next digit (9) of the dividend behind the 51 and repeat the process: 519 / 86

Let's proceed to step 4:
When dividing 519 by 86, we get 6 with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 16.0
The remainder is 3 after subtracting 516 from 519.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 86

Going ahead to step 5:
The number 86 fits into 39 0 times, leaving a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 160.0
If we take 0 away from 39, we end up with 39.
Append the next digit (0) from the dividend to 39 and continue with: 390 / 86

Step 6:
If we divide 390 by 86, we get 4 and a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 1604.0
Deduct 344 from 390 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 7:
When dividing 460 by 86, we get 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 1604.5
If we take 430 away from 460, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
86 can be fit into 300 3 times, resulting in a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 1604.53
The remainder is 42 after subtracting 258 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 9:
86 goes into 420 4 times with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 1604.534
Subtract 344 from 420 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 10:
If we divide 760 by 86, we get 8 and a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 1604.5348
The remainder is 72 after subtracting 688 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 11:
When dividing 720 by 86, we get 8 with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 1604.53488
If we take 688 away from 720, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 1604.53488 with a balance of 3.2e-05.
