We look at the division of 61738691 by 121 
Our goal is to divide 61738691 by 121.

Step 1:
The number 121 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 121

On to step 2:
When dividing 61 by 121, we get 0 with a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 61 to get 61.
Fetch the next digit (7) from the dividend, attach it to 61 and continue: 617 / 121

Step 3:
121 can be fit into 617 5 times, resulting in a remainder of 12.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 12 after subtracting 605 from 617.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 121

Let's proceed to step 4:
When dividing 123 by 121, we get 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
Subtracting 121 from 123 leaves us with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 121

Moving on to step 5:
When dividing 28 by 121, we get 0 with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 510.0
The remainder is 28 after subtracting 0 from 28.
Take the next digit (6) from the dividend and append it to 28, then repeat: 286 / 121

Going ahead to step 6:
If we divide 286 by 121, we get 2 and a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 5102.0
If we subtract 242 from 286, we get 44.
Include the next digit (9) from the dividend after 44, then repeat: 449 / 121

Going ahead to step 7:
449 divided by 121 is 3 with a remainder of 86.
Use 3 as the next digit of our solution. 
Result so far: 51023.0
If we subtract 363 from 449, we get 86.
Take the next digit (1) from the dividend and append it to 86, then repeat: 861 / 121

Going ahead to step 8:
If we divide 861 by 121, we get 7 and a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 510237.0
Subtract 847 from 861 to get 14.
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 9:
121 goes into 140 1 times with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 510237.1
Subtracting 121 from 140 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 10:
When dividing 190 by 121, we get 1 with a remainder of 69.
Record the quotient 1 as the next digit in the result. 
Result so far: 510237.11
If we take 121 away from 190, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

After the division, we end up with 510237.11 and a remainder of 0.069.
