15231191 ÷ 657 
We want to divide 15231191 by 657.

Moving on to step 1:
657 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 657

On to step 2:
If we divide 15 by 657, we get 0 and a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 657

On to step 3:
657 can be fit into 152 0 times, resulting in a remainder of 152.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 152 after subtracting 0 from 152.
Bring next digit (3) of the dividend behind the 152 and repeat the process: 1523 / 657

Advancing to step 4:
1523 divided by 657 is 2 with a remainder of 209.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 1314 from 1523 to get 209.
Grab the next digit (1) from the dividend, add it to 209, then carry on: 2091 / 657

Advancing to step 5:
657 goes into 2091 3 times with a remainder of 120.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
If we take 1971 away from 2091, we end up with 120.
Take the next digit (1) from the dividend and append it to 120, then repeat: 1201 / 657

On to step 6:
1201 divided by 657 is 1 with a remainder of 544.
The next digit of our result is 1. 
Result so far: 231.0
The remainder is 544 after subtracting 657 from 1201.
Grab the next digit (9) from the dividend, add it to 544, then carry on: 5449 / 657

Let's proceed to step 7:
657 goes into 5449 8 times with a remainder of 193.
The number 8 becomes the next digit in our result. 
Result so far: 2318.0
If we subtract 5256 from 5449, we get 193.
Grab the next digit (1) from the dividend, add it to 193, then carry on: 1931 / 657

Step 8:
657 goes into 1931 2 times with a remainder of 617.
Use 2 as the next digit of our solution. 
Result so far: 23182.0
Subtract 1314 from 1931 to get 617.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6170, and continue the process.

Going ahead to step 9:
657 goes into 6170 9 times with a remainder of 257.
Put 9 as the next digit of the answer. 
Result so far: 23182.9
If we subtract 5913 from 6170, we get 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Step 10:
2570 divided by 657 is 3 with a remainder of 599.
Record the quotient 3 as the next digit in the result. 
Result so far: 23182.93
Subtracting 1971 from 2570 leaves us with 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Let's proceed to step 11:
657 goes into 5990 9 times with a remainder of 77.
Record the quotient 9 as the next digit in the result. 
Result so far: 23182.939
If we subtract 5913 from 5990, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 12:
If we divide 770 by 657, we get 1 and a remainder of 113.
Use 1 as the next digit of our solution. 
Result so far: 23182.9391
Subtracting 657 from 770 leaves us with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Let's proceed to step 13:
657 can be fit into 1130 1 times, resulting in a remainder of 473.
Put 1 as the next digit of the answer. 
Result so far: 23182.93911
The remainder is 473 after subtracting 657 from 1130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

After the division, we end up with 23182.93911 and a remainder of 0.000473.
