We're dividing 421739 by 69 
We're looking to find how many times 69 goes into 421739.

Moving on to step 1:
The number 69 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 69

Advancing to step 2:
69 can be fit into 42 0 times, resulting in a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Bring next digit (1) of the dividend behind the 42 and repeat the process: 421 / 69

Moving on to step 3:
The number 69 fits into 421 6 times, leaving a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 414 from 421 leaves us with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 69

Moving on to step 4:
69 can be fit into 77 1 times, resulting in a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 61.0
Subtracting 69 from 77 leaves us with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 69

Going ahead to step 5:
When dividing 83 by 69, we get 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 611.0
Deduct 69 from 83 and we're left with 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 69

Going ahead to step 6:
149 divided by 69 is 2 with a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 6112.0
The remainder is 11 after subtracting 138 from 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
69 goes into 110 1 times with a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 6112.1
If we take 69 away from 110, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 8:
If we divide 410 by 69, we get 5 and a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 6112.15
If we take 345 away from 410, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 9:
650 divided by 69 is 9 with a remainder of 29.
The next digit of our result is 9. 
Result so far: 6112.159
Subtracting 621 from 650 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 10:
The number 69 fits into 290 4 times, leaving a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 6112.1594
The remainder is 14 after subtracting 276 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
The number 69 fits into 140 2 times, leaving a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 6112.15942
Subtract 138 from 140 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 12:
69 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 6112.15942
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
The number 69 fits into 200 2 times, leaving a remainder of 62.
The number 2 becomes the next digit in our result. 
Result so far: 6112.1594202
Subtract 138 from 200 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 14:
69 can be fit into 620 8 times, resulting in a remainder of 68.
Use 8 as the next digit of our solution. 
Result so far: 6112.15942028
Deduct 552 from 620 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final outcome is 6112.15942028, with a leftover of 6.8e-08.
