Let's divide 91107980 by 422
We want to figure out the number of times 91107980 can be divided by 422.

Let's proceed to step 1:
If we divide 9 by 422, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 422

Step 2:
91 divided by 422 is 0 with a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Include the next digit (1) from the dividend after 91, then repeat: 911 / 422

Going ahead to step 3:
When dividing 911 by 422, we get 2 with a remainder of 67.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 844 from 911 leaves us with 67.
Append the next digit (0) from the dividend to 67 and continue with: 670 / 422

Moving on to step 4:
The number 422 fits into 670 1 times, leaving a remainder of 248.
The next digit of our result is 1. 
Result so far: 21.0
If we take 422 away from 670, we end up with 248.
Bring next digit (7) of the dividend behind the 248 and repeat the process: 2487 / 422

On to step 5:
The number 422 fits into 2487 5 times, leaving a remainder of 377.
Use 5 as the next digit of our solution. 
Result so far: 215.0
Subtract 2110 from 2487 to get 377.
Fetch the next digit (9) from the dividend, attach it to 377 and continue: 3779 / 422

Advancing to step 6:
422 can be fit into 3779 8 times, resulting in a remainder of 403.
Put 8 as the next digit of the answer. 
Result so far: 2158.0
If we take 3376 away from 3779, we end up with 403.
Take the next digit (8) from the dividend and append it to 403, then repeat: 4038 / 422

Step 7:
The number 422 fits into 4038 9 times, leaving a remainder of 240.
Put 9 as the next digit of the answer. 
Result so far: 21589.0
Deduct 3798 from 4038 and we're left with 240.
Grab the next digit (0) from the dividend, add it to 240, then carry on: 2400 / 422

Let's proceed to step 8:
2400 divided by 422 is 5 with a remainder of 290.
Put 5 as the next digit of the answer. 
Result so far: 215895.0
The remainder is 290 after subtracting 2110 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 9:
422 can be fit into 2900 6 times, resulting in a remainder of 368.
Use 6 as the next digit of our solution. 
Result so far: 215895.6
The remainder is 368 after subtracting 2532 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Step 10:
422 can be fit into 3680 8 times, resulting in a remainder of 304.
Put 8 as the next digit of the answer. 
Result so far: 215895.68
Subtracting 3376 from 3680 leaves us with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 11:
422 can be fit into 3040 7 times, resulting in a remainder of 86.
Put 7 as the next digit of the answer. 
Result so far: 215895.687
The remainder is 86 after subtracting 2954 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 12:
If we divide 860 by 422, we get 2 and a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 215895.6872
Deduct 844 from 860 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
If we divide 160 by 422, we get 0 and a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 215895.6872
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 14:
1600 divided by 422 is 3 with a remainder of 334.
The next digit of our result is 3. 
Result so far: 215895.687203
If we take 1266 away from 1600, we end up with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Moving on to step 15:
The number 422 fits into 3340 7 times, leaving a remainder of 386.
Put 7 as the next digit of the answer. 
Result so far: 215895.6872037
Subtract 2954 from 3340 to get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Moving on to step 16:
422 can be fit into 3860 9 times, resulting in a remainder of 62.
Use 9 as the next digit of our solution. 
Result so far: 215895.68720379
Subtracting 3798 from 3860 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Our division results in 215895.68720379 with a remaining 6.2e-08.
