1397037 ÷ 86 
We want to figure out the number of times 1397037 can be divided by 86.

Moving on to step 1:
If we divide 1 by 86, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 86

On to step 2:
86 can be fit into 13 0 times, resulting in a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 86

Let's proceed to step 3:
139 divided by 86 is 1 with a remainder of 53.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 86 away from 139, we end up with 53.
Grab the next digit (7) from the dividend, add it to 53, then carry on: 537 / 86

Step 4:
86 goes into 537 6 times with a remainder of 21.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 21 after subtracting 516 from 537.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 86

Advancing to step 5:
86 can be fit into 210 2 times, resulting in a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 162.0
Subtracting 172 from 210 leaves us with 38.
Grab the next digit (3) from the dividend, add it to 38, then carry on: 383 / 86

Going ahead to step 6:
If we divide 383 by 86, we get 4 and a remainder of 39.
The next digit of our result is 4. 
Result so far: 1624.0
Deduct 344 from 383 and we're left with 39.
Bring next digit (7) of the dividend behind the 39 and repeat the process: 397 / 86

On to step 7:
The number 86 fits into 397 4 times, leaving a remainder of 53.
Use 4 as the next digit of our solution. 
Result so far: 16244.0
If we subtract 344 from 397, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 8:
86 can be fit into 530 6 times, resulting in a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 16244.6
Subtract 516 from 530 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
140 divided by 86 is 1 with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 16244.61
If we take 86 away from 140, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 10:
86 can be fit into 540 6 times, resulting in a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 16244.616
If we take 516 away from 540, we end up 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.

On to step 11:
If we divide 240 by 86, we get 2 and a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 16244.6162
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.

Let's proceed to step 12:
86 goes into 680 7 times with a remainder of 78.
Write down 7 as next digit of the result. 
Result so far: 16244.61627
Subtract 602 from 680 to get 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 13:
86 goes into 780 9 times with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 16244.616279
If we subtract 774 from 780, we get 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 14:
When dividing 60 by 86, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 16244.616279
If we subtract 0 from 60, we get 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 15:
600 divided by 86 is 6 with a remainder of 84.
The number 6 becomes the next digit in our result. 
Result so far: 16244.61627906
The remainder is 84 after subtracting 516 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Our division results in 16244.61627906 with a remaining 8.4e-08.
