20952021 ÷ 991 
We're looking to find how many times 991 goes into 20952021.

Step 1:
If we divide 2 by 991, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 991

Step 2:
991 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 991

On to step 3:
The number 991 fits into 209 0 times, leaving a remainder of 209.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 209 and we're left with 209.
Fetch the next digit (5) from the dividend, attach it to 209 and continue: 2095 / 991

On to step 4:
The number 991 fits into 2095 2 times, leaving a remainder of 113.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 1982 from 2095 to get 113.
Grab the next digit (2) from the dividend, add it to 113, then carry on: 1132 / 991

Advancing to step 5:
1132 divided by 991 is 1 with a remainder of 141.
The next digit of our result is 1. 
Result so far: 21.0
Subtract 991 from 1132 to get 141.
Include the next digit (0) from the dividend after 141, then repeat: 1410 / 991

Let's proceed to step 6:
If we divide 1410 by 991, we get 1 and a remainder of 419.
Use 1 as the next digit of our solution. 
Result so far: 211.0
Deduct 991 from 1410 and we're left with 419.
Append the next digit (2) from the dividend to 419 and continue with: 4192 / 991

Going ahead to step 7:
When dividing 4192 by 991, we get 4 with a remainder of 228.
Write down 4 as next digit of the result. 
Result so far: 2114.0
If we take 3964 away from 4192, we end up with 228.
Append the next digit (1) from the dividend to 228 and continue with: 2281 / 991

Moving on to step 8:
When dividing 2281 by 991, we get 2 with a remainder of 299.
Put 2 as the next digit of the answer. 
Result so far: 21142.0
Subtracting 1982 from 2281 leaves us 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.

Going ahead to step 9:
991 goes into 2990 3 times with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 21142.3
If we subtract 2973 from 2990, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 10:
When dividing 170 by 991, we get 0 with a remainder of 170.
Use 0 as the next digit of our solution. 
Result so far: 21142.3
Subtract 0 from 170 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 11:
991 goes into 1700 1 times with a remainder of 709.
Put 1 as the next digit of the answer. 
Result so far: 21142.301
Deduct 991 from 1700 and we're left with 709.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7090, and continue the process.

Step 12:
The number 991 fits into 7090 7 times, leaving a remainder of 153.
The number 7 becomes the next digit in our result. 
Result so far: 21142.3017
Deduct 6937 from 7090 and we're left with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

On to step 13:
991 goes into 1530 1 times with a remainder of 539.
Put 1 as the next digit of the answer. 
Result so far: 21142.30171
The remainder is 539 after subtracting 991 from 1530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Let's proceed to step 14:
5390 divided by 991 is 5 with a remainder of 435.
The next digit of our result is 5. 
Result so far: 21142.301715
Subtract 4955 from 5390 to get 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Advancing to step 15:
4350 divided by 991 is 4 with a remainder of 386.
Write down 4 as next digit of the result. 
Result so far: 21142.3017154
Subtract 3964 from 4350 to get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Step 16:
When dividing 3860 by 991, we get 3 with a remainder of 887.
Record the quotient 3 as the next digit in the result. 
Result so far: 21142.30171543
If we subtract 2973 from 3860, we get 887.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8870, and continue the process.

The final result is 21142.30171543 with a remainder of 8.87e-07.
