Let's divide 38866478 by 91
We're looking to find how many times 91 goes into 38866478.

Let's proceed 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.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 91

Step 2:
The number 91 fits into 38 0 times, leaving a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Bring next digit (8) of the dividend behind the 38 and repeat the process: 388 / 91

Advancing to step 3:
91 goes into 388 4 times with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 24 after subtracting 364 from 388.
Grab the next digit (6) from the dividend, add it to 24, then carry on: 246 / 91

On to step 4:
246 divided by 91 is 2 with a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
The remainder is 64 after subtracting 182 from 246.
Grab the next digit (6) from the dividend, add it to 64, then carry on: 646 / 91

Moving on to step 5:
When dividing 646 by 91, we get 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 427.0
The remainder is 9 after subtracting 637 from 646.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 91

Advancing to step 6:
91 goes into 94 1 times with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 4271.0
Deduct 91 from 94 and we're left with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 91

Moving on to step 7:
91 can be fit into 37 0 times, resulting in a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 42710.0
If we subtract 0 from 37, we get 37.
Include the next digit (8) from the dividend after 37, then repeat: 378 / 91

Advancing to step 8:
When dividing 378 by 91, we get 4 with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 427104.0
If we subtract 364 from 378, we 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.

Moving on to step 9:
91 can be fit into 140 1 times, resulting in a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 427104.1
If we take 91 away from 140, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 10:
When dividing 490 by 91, we get 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 427104.15
If we subtract 455 from 490, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 11:
91 goes into 350 3 times with a remainder of 77.
Put 3 as the next digit of the answer. 
Result so far: 427104.153
If we take 273 away from 350, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 12:
770 divided by 91 is 8 with a remainder of 42.
The next digit of our result is 8. 
Result so far: 427104.1538
Subtracting 728 from 770 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 13:
91 goes into 420 4 times with a remainder of 56.
The next digit of our result is 4. 
Result so far: 427104.15384
If we take 364 away from 420, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 14:
The number 91 fits into 560 6 times, leaving a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 427104.153846
If we take 546 away from 560, we end up with 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 15:
When dividing 140 by 91, we get 1 with a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 427104.1538461
If we take 91 away from 140, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 16:
If we divide 490 by 91, we get 5 and a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 427104.15384615
If we subtract 455 from 490, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 427104.15384615 and a remainder of 3.5e-08.
