We're dividing 91870563 by 597 
Our goal is to divide 91870563 by 597.

Step 1:
When dividing 9 by 597, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 597

Step 2:
The number 597 fits into 91 0 times, leaving a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Append the next digit (8) from the dividend to 91 and continue with: 918 / 597

Moving on to step 3:
918 divided by 597 is 1 with a remainder of 321.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 597 from 918 to get 321.
Take the next digit (7) from the dividend and append it to 321, then repeat: 3217 / 597

Step 4:
3217 divided by 597 is 5 with a remainder of 232.
The next digit of our result is 5. 
Result so far: 15.0
If we take 2985 away from 3217, we end up with 232.
Fetch the next digit (0) from the dividend, attach it to 232 and continue: 2320 / 597

Let's proceed to step 5:
597 goes into 2320 3 times with a remainder of 529.
Put 3 as the next digit of the answer. 
Result so far: 153.0
Subtracting 1791 from 2320 leaves us with 529.
Fetch the next digit (5) from the dividend, attach it to 529 and continue: 5295 / 597

Moving on to step 6:
When dividing 5295 by 597, we get 8 with a remainder of 519.
Put 8 as the next digit of the answer. 
Result so far: 1538.0
Subtracting 4776 from 5295 leaves us with 519.
Grab the next digit (6) from the dividend, add it to 519, then carry on: 5196 / 597

Let's proceed to step 7:
The number 597 fits into 5196 8 times, leaving a remainder of 420.
The next digit of our result is 8. 
Result so far: 15388.0
The remainder is 420 after subtracting 4776 from 5196.
Bring next digit (3) of the dividend behind the 420 and repeat the process: 4203 / 597

Going ahead to step 8:
The number 597 fits into 4203 7 times, leaving a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 153887.0
Subtract 4179 from 4203 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
When dividing 240 by 597, we get 0 with a remainder of 240.
The next digit of our result is 0. 
Result so far: 153887.0
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 10:
If we divide 2400 by 597, we get 4 and a remainder of 12.
The next digit of our result is 4. 
Result so far: 153887.04
If we subtract 2388 from 2400, 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.

Let's proceed to step 11:
597 goes into 120 0 times with a remainder of 120.
The next digit of our result is 0. 
Result so far: 153887.04
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.

Advancing to step 12:
597 goes into 1200 2 times with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 153887.0402
If we take 1194 away from 1200, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 13:
597 goes into 60 0 times with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 153887.0402
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 14:
597 can be fit into 600 1 times, resulting in a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 153887.040201
Subtracting 597 from 600 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 15:
When dividing 30 by 597, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 153887.040201
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 16:
597 can be fit into 300 0 times, resulting in a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 153887.040201
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final result is 153887.040201 with a remainder of 3e-07.
