We're dividing 42156721 by 701 
We want to divide 42156721 by 701.

Going ahead to step 1:
4 divided by 701 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 701

On to step 2:
701 goes into 42 0 times with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Fetch the next digit (1) from the dividend, attach it to 42 and continue: 421 / 701

Going ahead to step 3:
701 can be fit into 421 0 times, resulting in a remainder of 421.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 421 and we're left with 421.
Take the next digit (5) from the dividend and append it to 421, then repeat: 4215 / 701

On to step 4:
When dividing 4215 by 701, we get 6 with a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 9 after subtracting 4206 from 4215.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 701

On to step 5:
701 can be fit into 96 0 times, resulting in a remainder of 96.
Use 0 as the next digit of our solution. 
Result so far: 60.0
Deduct 0 from 96 and we're left with 96.
Grab the next digit (7) from the dividend, add it to 96, then carry on: 967 / 701

Step 6:
967 divided by 701 is 1 with a remainder of 266.
The next digit of our result is 1. 
Result so far: 601.0
If we subtract 701 from 967, we get 266.
Take the next digit (2) from the dividend and append it to 266, then repeat: 2662 / 701

On to step 7:
701 goes into 2662 3 times with a remainder of 559.
Write down 3 as next digit of the result. 
Result so far: 6013.0
Subtracting 2103 from 2662 leaves us with 559.
Bring next digit (1) of the dividend behind the 559 and repeat the process: 5591 / 701

Going ahead to step 8:
5591 divided by 701 is 7 with a remainder of 684.
Record the quotient 7 as the next digit in the result. 
Result so far: 60137.0
Subtract 4907 from 5591 to get 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

On to step 9:
The number 701 fits into 6840 9 times, leaving a remainder of 531.
Use 9 as the next digit of our solution. 
Result so far: 60137.9
Subtracting 6309 from 6840 leaves us with 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

On to step 10:
701 goes into 5310 7 times with a remainder of 403.
The next digit of our result is 7. 
Result so far: 60137.97
If we subtract 4907 from 5310, we get 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

On to step 11:
When dividing 4030 by 701, we get 5 with a remainder of 525.
Use 5 as the next digit of our solution. 
Result so far: 60137.975
If we take 3505 away from 4030, we end up with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Moving on to step 12:
701 goes into 5250 7 times with a remainder of 343.
Record the quotient 7 as the next digit in the result. 
Result so far: 60137.9757
Deduct 4907 from 5250 and we're left with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Let's proceed to step 13:
701 goes into 3430 4 times with a remainder of 626.
Put 4 as the next digit of the answer. 
Result so far: 60137.97574
Deduct 2804 from 3430 and we're left with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Moving on to step 14:
When dividing 6260 by 701, we get 8 with a remainder of 652.
The next digit of our result is 8. 
Result so far: 60137.975748
If we subtract 5608 from 6260, we get 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Let's proceed to step 15:
701 can be fit into 6520 9 times, resulting in a remainder of 211.
Use 9 as the next digit of our solution. 
Result so far: 60137.9757489
If we take 6309 away from 6520, we end up with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Let's proceed to step 16:
When dividing 2110 by 701, we get 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 60137.97574893
Deduct 2103 from 2110 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 60137.97574893, with a leftover of 7e-09.
