15420299 divided by 691 
We're looking to find how many times 691 goes into 15420299.

Step 1:
When dividing 1 by 691, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 691

Step 2:
When dividing 15 by 691, we get 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 691

Going ahead to step 3:
691 can be fit into 154 0 times, resulting in a remainder of 154.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 154, we get 154.
Include the next digit (2) from the dividend after 154, then repeat: 1542 / 691

Going ahead to step 4:
If we divide 1542 by 691, we get 2 and a remainder of 160.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1382 from 1542, we get 160.
Bring next digit (0) of the dividend behind the 160 and repeat the process: 1600 / 691

Advancing to step 5:
691 can be fit into 1600 2 times, resulting in a remainder of 218.
Use 2 as the next digit of our solution. 
Result so far: 22.0
The remainder is 218 after subtracting 1382 from 1600.
Grab the next digit (2) from the dividend, add it to 218, then carry on: 2182 / 691

Going ahead to step 6:
The number 691 fits into 2182 3 times, leaving a remainder of 109.
The number 3 becomes the next digit in our result. 
Result so far: 223.0
If we take 2073 away from 2182, we end up with 109.
Append the next digit (9) from the dividend to 109 and continue with: 1099 / 691

On to step 7:
1099 divided by 691 is 1 with a remainder of 408.
Use 1 as the next digit of our solution. 
Result so far: 2231.0
If we subtract 691 from 1099, we get 408.
Take the next digit (9) from the dividend and append it to 408, then repeat: 4089 / 691

Let's proceed to step 8:
691 goes into 4089 5 times with a remainder of 634.
The number 5 becomes the next digit in our result. 
Result so far: 22315.0
The remainder is 634 after subtracting 3455 from 4089.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Let's proceed to step 9:
691 goes into 6340 9 times with a remainder of 121.
The next digit of our result is 9. 
Result so far: 22315.9
Deduct 6219 from 6340 and we're left with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Advancing to step 10:
When dividing 1210 by 691, we get 1 with a remainder of 519.
The next digit of our result is 1. 
Result so far: 22315.91
If we take 691 away from 1210, we end up with 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Let's proceed to step 11:
If we divide 5190 by 691, we get 7 and a remainder of 353.
Record the quotient 7 as the next digit in the result. 
Result so far: 22315.917
If we subtract 4837 from 5190, we get 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

On to step 12:
691 goes into 3530 5 times with a remainder of 75.
The next digit of our result is 5. 
Result so far: 22315.9175
If we take 3455 away from 3530, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 13:
691 goes into 750 1 times with a remainder of 59.
The next digit of our result is 1. 
Result so far: 22315.91751
Deduct 691 from 750 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 14:
590 divided by 691 is 0 with a remainder of 590.
The number 0 becomes the next digit in our result. 
Result so far: 22315.91751
If we subtract 0 from 590, we get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Moving on to step 15:
When dividing 5900 by 691, we get 8 with a remainder of 372.
The number 8 becomes the next digit in our result. 
Result so far: 22315.9175108
Subtracting 5528 from 5900 leaves us with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Going ahead to step 16:
The number 691 fits into 3720 5 times, leaving a remainder of 265.
The next digit of our result is 5. 
Result so far: 22315.91751085
Deduct 3455 from 3720 and we're left with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

The final outcome is 22315.91751085, with a leftover of 2.65e-07.
