Let's divide 351340 by 91
We're looking to find how many times 91 goes into 351340.

Step 1:
When dividing 3 by 91, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 91

Step 2:
91 goes into 35 0 times with a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Grab the next digit (1) from the dividend, add it to 35, then carry on: 351 / 91

Let's proceed to step 3:
91 can be fit into 351 3 times, resulting in a remainder of 78.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 273 from 351, we get 78.
Bring next digit (3) of the dividend behind the 78 and repeat the process: 783 / 91

Let's proceed to step 4:
If we divide 783 by 91, we get 8 and a remainder of 55.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Subtracting 728 from 783 leaves us with 55.
Append the next digit (4) from the dividend to 55 and continue with: 554 / 91

Step 5:
554 divided by 91 is 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 386.0
Deduct 546 from 554 and we're left with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 91

On to step 6:
80 divided by 91 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 3860.0
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 7:
91 goes into 800 8 times with a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 3860.8
The remainder is 72 after subtracting 728 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 8:
720 divided by 91 is 7 with a remainder of 83.
Record the quotient 7 as the next digit in the result. 
Result so far: 3860.87
Subtract 637 from 720 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 9:
91 can be fit into 830 9 times, resulting in a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 3860.879
If we subtract 819 from 830, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 10:
If we divide 110 by 91, we get 1 and a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 3860.8791
If we subtract 91 from 110, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 11:
If we divide 190 by 91, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 3860.87912
Deduct 182 from 190 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
80 divided by 91 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 3860.87912
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 13:
The number 91 fits into 800 8 times, leaving a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 3860.8791208
Deduct 728 from 800 and we're left with 72.
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 14:
720 divided by 91 is 7 with a remainder of 83.
Record the quotient 7 as the next digit in the result. 
Result so far: 3860.87912087
The remainder is 83 after subtracting 637 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

The quotient of the division is 3860.87912087, and the remainder is 8.3e-08.
