We look at the division of 340986 by 91 
Let's see how many times 91 fits into 340986.

On to step 1:
91 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 91

Step 2:
91 goes into 34 0 times with a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Take the next digit (0) from the dividend and append it to 34, then repeat: 340 / 91

On to step 3:
If we divide 340 by 91, we get 3 and a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 273 from 340 leaves us with 67.
Take the next digit (9) from the dividend and append it to 67, then repeat: 679 / 91

On to step 4:
When dividing 679 by 91, we get 7 with a remainder of 42.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
The remainder is 42 after subtracting 637 from 679.
Bring next digit (8) of the dividend behind the 42 and repeat the process: 428 / 91

Moving on to step 5:
91 goes into 428 4 times with a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 374.0
Subtracting 364 from 428 leaves us with 64.
Take the next digit (6) from the dividend and append it to 64, then repeat: 646 / 91

Advancing to step 6:
646 divided by 91 is 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 3747.0
If we subtract 637 from 646, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
91 can be fit into 90 0 times, resulting in a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 3747.0
Subtract 0 from 90 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 8:
900 divided by 91 is 9 with a remainder of 81.
The next digit of our result is 9. 
Result so far: 3747.09
If we subtract 819 from 900, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 9:
91 can be fit into 810 8 times, resulting in a remainder of 82.
Use 8 as the next digit of our solution. 
Result so far: 3747.098
If we subtract 728 from 810, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 10:
91 goes into 820 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 3747.0989
If we take 819 away from 820, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 11:
If we divide 10 by 91, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 3747.0989
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
When dividing 100 by 91, we get 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 3747.098901
If we subtract 91 from 100, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 13:
91 goes into 90 0 times with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 3747.098901
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 14:
If we divide 900 by 91, we get 9 and a remainder of 81.
Use 9 as the next digit of our solution. 
Result so far: 3747.09890109
Subtract 819 from 900 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

The quotient of the division is 3747.09890109, and the remainder is 8.1e-08.
