91097710 ÷ 148 
Our goal is to divide 91097710 by 148.

Step 1:
When dividing 9 by 148, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 148

Advancing to step 2:
When dividing 91 by 148, we get 0 with a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Fetch the next digit (0) from the dividend, attach it to 91 and continue: 910 / 148

Moving on to step 3:
If we divide 910 by 148, we get 6 and a remainder of 22.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 22 after subtracting 888 from 910.
Bring next digit (9) of the dividend behind the 22 and repeat the process: 229 / 148

Step 4:
229 divided by 148 is 1 with a remainder of 81.
The next digit of our result is 1. 
Result so far: 61.0
If we take 148 away from 229, we end up with 81.
Grab the next digit (7) from the dividend, add it to 81, then carry on: 817 / 148

Advancing to step 5:
If we divide 817 by 148, we get 5 and a remainder of 77.
Write down 5 as next digit of the result. 
Result so far: 615.0
If we subtract 740 from 817, we get 77.
Grab the next digit (7) from the dividend, add it to 77, then carry on: 777 / 148

Let's proceed to step 6:
The number 148 fits into 777 5 times, leaving a remainder of 37.
The number 5 becomes the next digit in our result. 
Result so far: 6155.0
The remainder is 37 after subtracting 740 from 777.
Include the next digit (1) from the dividend after 37, then repeat: 371 / 148

On to step 7:
When dividing 371 by 148, we get 2 with a remainder of 75.
Record the quotient 2 as the next digit in the result. 
Result so far: 61552.0
The remainder is 75 after subtracting 296 from 371.
Bring next digit (0) of the dividend behind the 75 and repeat the process: 750 / 148

Advancing to step 8:
750 divided by 148 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 615525.0
Subtract 740 from 750 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
The number 148 fits into 100 0 times, leaving a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 615525.0
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 10:
148 can be fit into 1000 6 times, resulting in a remainder of 112.
Record the quotient 6 as the next digit in the result. 
Result so far: 615525.06
Deduct 888 from 1000 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 11:
148 goes into 1120 7 times with a remainder of 84.
Record the quotient 7 as the next digit in the result. 
Result so far: 615525.067
The remainder is 84 after subtracting 1036 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 12:
When dividing 840 by 148, we get 5 with a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 615525.0675
If we subtract 740 from 840, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 13:
If we divide 1000 by 148, we get 6 and a remainder of 112.
Record the quotient 6 as the next digit in the result. 
Result so far: 615525.06756
Subtracting 888 from 1000 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 14:
When dividing 1120 by 148, we get 7 with a remainder of 84.
The number 7 becomes the next digit in our result. 
Result so far: 615525.067567
The remainder is 84 after subtracting 1036 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 15:
When dividing 840 by 148, we get 5 with a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 615525.0675675
Subtracting 740 from 840 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 16:
148 can be fit into 1000 6 times, resulting in a remainder of 112.
The number 6 becomes the next digit in our result. 
Result so far: 615525.06756756
Deduct 888 from 1000 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The final result is 615525.06756756 with a remainder of 1.12e-07.
