We divide 90191021 by 977
We want to figure out the number of times 90191021 can be divided by 977.

Let's proceed to step 1:
The number 977 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 977

Going ahead to step 2:
The number 977 fits into 90 0 times, leaving a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Fetch the next digit (1) from the dividend, attach it to 90 and continue: 901 / 977

Moving on to step 3:
901 divided by 977 is 0 with a remainder of 901.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 901 after subtracting 0 from 901.
Fetch the next digit (9) from the dividend, attach it to 901 and continue: 9019 / 977

Let's proceed to step 4:
The number 977 fits into 9019 9 times, leaving a remainder of 226.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 8793 from 9019 and we're left with 226.
Fetch the next digit (1) from the dividend, attach it to 226 and continue: 2261 / 977

Advancing to step 5:
977 goes into 2261 2 times with a remainder of 307.
The next digit of our result is 2. 
Result so far: 92.0
The remainder is 307 after subtracting 1954 from 2261.
Append the next digit (0) from the dividend to 307 and continue with: 3070 / 977

Going ahead to step 6:
If we divide 3070 by 977, we get 3 and a remainder of 139.
The next digit of our result is 3. 
Result so far: 923.0
If we take 2931 away from 3070, we end up with 139.
Bring next digit (2) of the dividend behind the 139 and repeat the process: 1392 / 977

Step 7:
If we divide 1392 by 977, we get 1 and a remainder of 415.
The next digit of our result is 1. 
Result so far: 9231.0
If we subtract 977 from 1392, we get 415.
Fetch the next digit (1) from the dividend, attach it to 415 and continue: 4151 / 977

Let's proceed to step 8:
The number 977 fits into 4151 4 times, leaving a remainder of 243.
Put 4 as the next digit of the answer. 
Result so far: 92314.0
The remainder is 243 after subtracting 3908 from 4151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Let's proceed to step 9:
If we divide 2430 by 977, we get 2 and a remainder of 476.
Put 2 as the next digit of the answer. 
Result so far: 92314.2
Deduct 1954 from 2430 and we're left with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Let's proceed to step 10:
The number 977 fits into 4760 4 times, leaving a remainder of 852.
The next digit of our result is 4. 
Result so far: 92314.24
If we subtract 3908 from 4760, we get 852.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8520, and continue the process.

Step 11:
977 goes into 8520 8 times with a remainder of 704.
Write down 8 as next digit of the result. 
Result so far: 92314.248
If we take 7816 away from 8520, we end up with 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Advancing to step 12:
The number 977 fits into 7040 7 times, leaving a remainder of 201.
Write down 7 as next digit of the result. 
Result so far: 92314.2487
Subtract 6839 from 7040 to get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Going ahead to step 13:
977 goes into 2010 2 times with a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 92314.24872
If we take 1954 away from 2010, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 14:
When dividing 560 by 977, we get 0 with a remainder of 560.
Write down 0 as next digit of the result. 
Result so far: 92314.24872
Subtracting 0 from 560 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 15:
5600 divided by 977 is 5 with a remainder of 715.
Put 5 as the next digit of the answer. 
Result so far: 92314.2487205
If we take 4885 away from 5600, we end up with 715.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7150, and continue the process.

Going ahead to step 16:
The number 977 fits into 7150 7 times, leaving a remainder of 311.
Put 7 as the next digit of the answer. 
Result so far: 92314.24872057
If we subtract 6839 from 7150, we get 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

The final result is 92314.24872057 with a remainder of 3.11e-07.
