When dividing 4421 by 691, we get 6 with a remainder of 275.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
Subtracting 4146 from 4421 leaves us with 275.
Append the next digit (6) from the dividend to 275 and continue with: 2756 / 691

Going ahead to step 6:
691 can be fit into 2756 3 times, resulting in a remainder of 683.
The next digit of our result is 3. 
Result so far: 563.0
Subtract 2073 from 2756 to get 683.
Take the next digit (9) from the dividend and append it to 683, then repeat: 6839 / 691

Moving on to step 7:
If we divide 6839 by 691, we get 9 and a remainder of 620.
The next digit of our result is 9. 
Result so far: 5639.0
Subtract 6219 from 6839 to get 620.
Append the next digit (2) from the dividend to 620 and continue with: 6202 / 691

Moving on to step 8:
6202 divided by 691 is 8 with a remainder of 674.
Put 8 as the next digit of the answer. 
Result so far: 56398.0
If we take 5528 away from 6202, we end up with 674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6740, and continue the process.

Going ahead to step 9:
6740 divided by 691 is 9 with a remainder of 521.
The number 9 becomes the next digit in our result. 
Result so far: 56398.9
If we subtract 6219 from 6740, we get 521.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5210, and continue the process.

Step 10:
If we divide 5210 by 691, we get 7 and a remainder of 373.
Put 7 as the next digit of the answer. 
Result so far: 56398.97
If we subtract 4837 from 5210, we get 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Moving on to step 11:
3730 divided by 691 is 5 with a remainder of 275.
Use 5 as the next digit of our solution. 
Result so far: 56398.975
If we subtract 3455 from 3730, we get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Advancing to step 12:
The number 691 fits into 2750 3 times, leaving a remainder of 677.
Record the quotient 3 as the next digit in the result. 
Result so far: 56398.9753
Subtract 2073 from 2750 to get 677.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6770, and continue the process.

Advancing to step 13:
If we divide 6770 by 691, we get 9 and a remainder of 551.
Put 9 as the next digit of the answer. 
Result so far: 56398.97539
If we subtract 6219 from 6770, we get 551.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

Moving on to step 14:
The number 691 fits into 5510 7 times, leaving a remainder of 673.
Write down 7 as next digit of the result. 
Result so far: 56398.975397
Subtracting 4837 from 5510 leaves us with 673.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6730, and continue the process.

Moving on to step 15:
6730 divided by 691 is 9 with a remainder of 511.
Record the quotient 9 as the next digit in the result. 
Result so far: 56398.9753979
Subtracting 6219 from 6730 leaves us with 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Step 16:
If we divide 5110 by 691, we get 7 and a remainder of 273.
Use 7 as the next digit of our solution. 
Result so far: 56398.97539797
If we take 4837 away from 5110, we end up with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

In conclusion, the division gives 56398.97539797 with a balance of 2.73e-07.
