12207056 ÷ 921 
Our goal is to divide 12207056 by 921.

Step 1:
921 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 921

Moving on to step 2:
If we divide 12 by 921, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 921

Advancing to step 3:
When dividing 122 by 921, we get 0 with a remainder of 122.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 122 leaves us with 122.
Grab the next digit (0) from the dividend, add it to 122, then carry on: 1220 / 921

Let's proceed to step 4:
If we divide 1220 by 921, we get 1 and a remainder of 299.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 921 from 1220 leaves us with 299.
Take the next digit (7) from the dividend and append it to 299, then repeat: 2997 / 921

Going ahead to step 5:
921 goes into 2997 3 times with a remainder of 234.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 2763 from 2997 leaves us with 234.
Append the next digit (0) from the dividend to 234 and continue with: 2340 / 921

Step 6:
If we divide 2340 by 921, we get 2 and a remainder of 498.
Use 2 as the next digit of our solution. 
Result so far: 132.0
If we take 1842 away from 2340, we end up with 498.
Take the next digit (5) from the dividend and append it to 498, then repeat: 4985 / 921

On to step 7:
If we divide 4985 by 921, we get 5 and a remainder of 380.
Record the quotient 5 as the next digit in the result. 
Result so far: 1325.0
The remainder is 380 after subtracting 4605 from 4985.
Grab the next digit (6) from the dividend, add it to 380, then carry on: 3806 / 921

Step 8:
921 goes into 3806 4 times with a remainder of 122.
Record the quotient 4 as the next digit in the result. 
Result so far: 13254.0
If we subtract 3684 from 3806, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 9:
The number 921 fits into 1220 1 times, leaving a remainder of 299.
The next digit of our result is 1. 
Result so far: 13254.1
Deduct 921 from 1220 and we're left with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

On to step 10:
When dividing 2990 by 921, we get 3 with a remainder of 227.
Record the quotient 3 as the next digit in the result. 
Result so far: 13254.13
Subtracting 2763 from 2990 leaves us with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

On to step 11:
When dividing 2270 by 921, we get 2 with a remainder of 428.
Put 2 as the next digit of the answer. 
Result so far: 13254.132
Deduct 1842 from 2270 and we're left with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Step 12:
921 can be fit into 4280 4 times, resulting in a remainder of 596.
Record the quotient 4 as the next digit in the result. 
Result so far: 13254.1324
If we subtract 3684 from 4280, we get 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Advancing to step 13:
5960 divided by 921 is 6 with a remainder of 434.
Record the quotient 6 as the next digit in the result. 
Result so far: 13254.13246
Subtract 5526 from 5960 to get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Moving on to step 14:
921 goes into 4340 4 times with a remainder of 656.
The number 4 becomes the next digit in our result. 
Result so far: 13254.132464
Subtracting 3684 from 4340 leaves us with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Let's proceed to step 15:
The number 921 fits into 6560 7 times, leaving a remainder of 113.
The number 7 becomes the next digit in our result. 
Result so far: 13254.1324647
Subtract 6447 from 6560 to get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

On to step 16:
921 can be fit into 1130 1 times, resulting in a remainder of 209.
The number 1 becomes the next digit in our result. 
Result so far: 13254.13246471
If we subtract 921 from 1130, we get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Our division results in 13254.13246471 with a remaining 2.09e-07.
