We're dividing 42126870 by 691 
Our goal is to divide 42126870 by 691.

Let's proceed to step 1:
If we divide 4 by 691, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 691

Moving on to step 2:
42 divided by 691 is 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Grab the next digit (1) from the dividend, add it to 42, then carry on: 421 / 691

Step 3:
691 goes into 421 0 times with a remainder of 421.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 421 to get 421.
Bring next digit (2) of the dividend behind the 421 and repeat the process: 4212 / 691

On to step 4:
4212 divided by 691 is 6 with a remainder of 66.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 4146 away from 4212, we end up with 66.
Fetch the next digit (6) from the dividend, attach it to 66 and continue: 666 / 691

Step 5:
666 divided by 691 is 0 with a remainder of 666.
The next digit of our result is 0. 
Result so far: 60.0
Subtract 0 from 666 to get 666.
Grab the next digit (8) from the dividend, add it to 666, then carry on: 6668 / 691

On to step 6:
691 can be fit into 6668 9 times, resulting in a remainder of 449.
The number 9 becomes the next digit in our result. 
Result so far: 609.0
The remainder is 449 after subtracting 6219 from 6668.
Fetch the next digit (7) from the dividend, attach it to 449 and continue: 4497 / 691

Advancing to step 7:
691 goes into 4497 6 times with a remainder of 351.
Put 6 as the next digit of the answer. 
Result so far: 6096.0
Subtract 4146 from 4497 to get 351.
Append the next digit (0) from the dividend to 351 and continue with: 3510 / 691

Going ahead to step 8:
The number 691 fits into 3510 5 times, leaving a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 60965.0
Deduct 3455 from 3510 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 9:
If we divide 550 by 691, we get 0 and a remainder of 550.
Put 0 as the next digit of the answer. 
Result so far: 60965.0
If we take 0 away from 550, we end up with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Step 10:
691 goes into 5500 7 times with a remainder of 663.
The number 7 becomes the next digit in our result. 
Result so far: 60965.07
If we take 4837 away from 5500, we end up with 663.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

Going ahead to step 11:
691 goes into 6630 9 times with a remainder of 411.
Record the quotient 9 as the next digit in the result. 
Result so far: 60965.079
Subtract 6219 from 6630 to get 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Step 12:
691 goes into 4110 5 times with a remainder of 655.
Write down 5 as next digit of the result. 
Result so far: 60965.0795
Subtracting 3455 from 4110 leaves us with 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

Advancing to step 13:
6550 divided by 691 is 9 with a remainder of 331.
Put 9 as the next digit of the answer. 
Result so far: 60965.07959
Deduct 6219 from 6550 and we're left with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Let's proceed to step 14:
691 goes into 3310 4 times with a remainder of 546.
Put 4 as the next digit of the answer. 
Result so far: 60965.079594
The remainder is 546 after subtracting 2764 from 3310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Let's proceed to step 15:
If we divide 5460 by 691, we get 7 and a remainder of 623.
Write down 7 as next digit of the result. 
Result so far: 60965.0795947
If we subtract 4837 from 5460, we get 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

On to step 16:
If we divide 6230 by 691, we get 9 and a remainder of 11.
The next digit of our result is 9. 
Result so far: 60965.07959479
If we take 6219 away from 6230, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final outcome is 60965.07959479, with a leftover of 1.1e-08.
