We look at the division of 345986 by 91 
Let's see how many times 91 fits into 345986.

Moving on to step 1:
When dividing 3 by 91, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 91

Let's proceed to step 2:
The number 91 fits into 34 0 times, leaving a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Take the next digit (5) from the dividend and append it to 34, then repeat: 345 / 91

Going ahead to step 3:
If we divide 345 by 91, we get 3 and a remainder of 72.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 273 from 345 and we're left with 72.
Append the next digit (9) from the dividend to 72 and continue with: 729 / 91

Going ahead to step 4:
729 divided by 91 is 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
The remainder is 1 after subtracting 728 from 729.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 91

On to step 5:
If we divide 18 by 91, we get 0 and a remainder of 18.
The next digit of our result is 0. 
Result so far: 380.0
If we take 0 away from 18, we end up with 18.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 91

Let's proceed to step 6:
91 can be fit into 186 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 3802.0
If we take 182 away from 186, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
The number 91 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 3802.0
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
The number 91 fits into 400 4 times, leaving a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 3802.04
The remainder is 36 after subtracting 364 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
91 goes into 360 3 times with a remainder of 87.
Put 3 as the next digit of the answer. 
Result so far: 3802.043
If we take 273 away from 360, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 10:
91 can be fit into 870 9 times, resulting in a remainder of 51.
The number 9 becomes the next digit in our result. 
Result so far: 3802.0439
The remainder is 51 after subtracting 819 from 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 11:
510 divided by 91 is 5 with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 3802.04395
If we subtract 455 from 510, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 12:
When dividing 550 by 91, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 3802.043956
Subtracting 546 from 550 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 13:
If we divide 40 by 91, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 3802.043956
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 14:
91 can be fit into 400 4 times, resulting in a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 3802.04395604
The remainder is 36 after subtracting 364 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The quotient of the division is 3802.04395604, and the remainder is 3.6e-08.
