376421 divided by 91 
Our goal is to divide 376421 by 91.

Advancing to step 1:
When dividing 3 by 91, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 91

Moving on to step 2:
91 can be fit into 37 0 times, resulting in a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Grab the next digit (6) from the dividend, add it to 37, then carry on: 376 / 91

Step 3:
The number 91 fits into 376 4 times, leaving a remainder of 12.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 12 after subtracting 364 from 376.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 91

Advancing to step 4:
124 divided by 91 is 1 with a remainder of 33.
The next digit of our result is 1. 
Result so far: 41.0
Subtracting 91 from 124 leaves us with 33.
Fetch the next digit (2) from the dividend, attach it to 33 and continue: 332 / 91

Step 5:
The number 91 fits into 332 3 times, leaving a remainder of 59.
The number 3 becomes the next digit in our result. 
Result so far: 413.0
Deduct 273 from 332 and we're left with 59.
Fetch the next digit (1) from the dividend, attach it to 59 and continue: 591 / 91

Moving on to step 6:
91 can be fit into 591 6 times, resulting in a remainder of 45.
Use 6 as the next digit of our solution. 
Result so far: 4136.0
If we subtract 546 from 591, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 7:
450 divided by 91 is 4 with a remainder of 86.
Use 4 as the next digit of our solution. 
Result so far: 4136.4
If we take 364 away from 450, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 8:
91 goes into 860 9 times with a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 4136.49
The remainder is 41 after subtracting 819 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 9:
When dividing 410 by 91, we get 4 with a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 4136.494
Subtract 364 from 410 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 10:
91 goes into 460 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 4136.4945
Subtracting 455 from 460 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 11:
If we divide 50 by 91, we get 0 and a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 4136.4945
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
When dividing 500 by 91, we get 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 4136.494505
Deduct 455 from 500 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 13:
If we divide 450 by 91, we get 4 and a remainder of 86.
Put 4 as the next digit of the answer. 
Result so far: 4136.4945054
Subtracting 364 from 450 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 14:
The number 91 fits into 860 9 times, leaving a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 4136.49450549
The remainder is 41 after subtracting 819 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

The final outcome is 4136.49450549, with a leftover of 4.1e-08.
