We look at the division of 91580103 by 214 
We want to divide 91580103 by 214.

Step 1:
214 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 214

Step 2:
214 can be fit into 91 0 times, resulting in a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Bring next digit (5) of the dividend behind the 91 and repeat the process: 915 / 214

Advancing to step 3:
If we divide 915 by 214, we get 4 and a remainder of 59.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 59 after subtracting 856 from 915.
Append the next digit (8) from the dividend to 59 and continue with: 598 / 214

Let's proceed to step 4:
If we divide 598 by 214, we get 2 and a remainder of 170.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Subtracting 428 from 598 leaves us with 170.
Bring next digit (0) of the dividend behind the 170 and repeat the process: 1700 / 214

Going ahead to step 5:
214 can be fit into 1700 7 times, resulting in a remainder of 202.
The number 7 becomes the next digit in our result. 
Result so far: 427.0
The remainder is 202 after subtracting 1498 from 1700.
Bring next digit (1) of the dividend behind the 202 and repeat the process: 2021 / 214

Advancing to step 6:
If we divide 2021 by 214, we get 9 and a remainder of 95.
Record the quotient 9 as the next digit in the result. 
Result so far: 4279.0
Subtract 1926 from 2021 to get 95.
Fetch the next digit (0) from the dividend, attach it to 95 and continue: 950 / 214

On to step 7:
214 can be fit into 950 4 times, resulting in a remainder of 94.
The number 4 becomes the next digit in our result. 
Result so far: 42794.0
The remainder is 94 after subtracting 856 from 950.
Append the next digit (3) from the dividend to 94 and continue with: 943 / 214

Let's proceed to step 8:
When dividing 943 by 214, we get 4 with a remainder of 87.
Record the quotient 4 as the next digit in the result. 
Result so far: 427944.0
Subtract 856 from 943 to get 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 9:
214 can be fit into 870 4 times, resulting in a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 427944.4
Deduct 856 from 870 and we're left 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.

On to step 10:
The number 214 fits into 140 0 times, leaving a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 427944.4
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 11:
When dividing 1400 by 214, we get 6 with a remainder of 116.
Record the quotient 6 as the next digit in the result. 
Result so far: 427944.406
If we take 1284 away from 1400, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Advancing to step 12:
If we divide 1160 by 214, we get 5 and a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 427944.4065
Subtract 1070 from 1160 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 13:
900 divided by 214 is 4 with a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 427944.40654
Subtract 856 from 900 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 14:
When dividing 440 by 214, we get 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 427944.406542
If we subtract 428 from 440, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 15:
214 can be fit into 120 0 times, resulting in a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 427944.406542
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 16:
1200 divided by 214 is 5 with a remainder of 130.
Write down 5 as next digit of the result. 
Result so far: 427944.40654205
The remainder is 130 after subtracting 1070 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

The final result is 427944.40654205 with a remainder of 1.3e-07.
